I have contacted many remote viewers online, yes, what's the point?
;D
No, seriously. Contacted by
whom? You didn't specify. Remote viewers contact each other all the time, you just contacted me, too

Do you mean some Oh So Shady Organization? Sorry, I have just bumped into online paranoia in an other group as well and that's why I might come across as a bit too aggressive. It's as if today were Conspiracy Day or something. Cut it out already, people. You're telling stories but it always happened to a friend of someone you knew, or you heard it from the other guy...
Well look Eric, if I were The Government, I could contact you because you have an e-mail address, even if it's some free one (I dunno offhand) or I could send you a private msg on boards, so what now, will you not post or do anything online because someone might be watching?! Obviously not.
But. I have designed and run experiments - completely mainstream psychology experiments - and that's something most people never do in their entire lives so they don't know how it is. I'll tell you now. (Most researchers would rather not talk about this because it's less than glamorous LOL. At least I don't see them talk about it... oh whatever. I'm still a student, on no one's payroll, so I can say how I feel.)
Very often, the worst part of doing an experiment is... not the math. Not the design. Not the idunnowhat. The worst part is,
finding participants and getting them to do what they're supposed to do - let me clarify on this latter part... Eg. if some apparatus is needed, then the participants should be in the same room as the apparatus, and if that means they have to be flown in from halfway across the country, or you have to go there with the apparatus it just won't work, not in the long term.
So. Let's cut to the chase and say you're the army (of your choice) and want to do some top secret psi research. Where do you look for your participants?
(No, not online. But hear me out and you'll see why.)
First of all, you need them fairly soon. And you need them to be trustworthy because heck, this is a top secret operation. The people who are
already in the army (intelligence organization, secret police, whatever) already have the necessary clearances to work on this stuff or even if they don't, it takes them a lot less time than for someone you pick off the street and induct to the army, have'im do the whole thing from scratch.
If you just find some random people online... well that's a huge security risk for your organization! Even if they're US citizens, they might work for foreign intell agencies, have allegations, etc. that you need to check. And that takes a long time, and if they're foreign spies and have done all that online posting to attract attention on themselves, then they're obviously well-prepared for security checks. (Though I don't think they would do that, because no secret project searches online for participants anyway... at least I haven't seen any!) Now compare that to someone who has been in the army from a young age, used to the structure of the army,
used to following orders which is not necessarily common in the outside world, with all that emphasis the US puts on individuality, be yourself, listen to your heart, all that stuff... you just can't compare. Even if they're not spies, with interests deliberately opposed to yours, rather ordinary people like to gossip every now and then, and now all this strictness all of a sudden... oy vey!
The army is HUGE and you don't need 100 remote viewers, you only need a handful. So you can find a couple of very good remote viewers, one-in-a-thousand types, even in the army, no need to go to the civilian world. Keep it in-house.
Plus (and this is a huge plus) the army has the means to get a large amount of people to do whatever it thinks they should be doing. If it wants them to do a remote viewing test, it'll just command'em to do it. It has buildings, logistics, everything.
(With an online test you can also have many people but you have no control of their surroundings, which might be a disadvantage. I confess, I have done RV sessions online while simultaneously reading incoming e-mail. LOL)
The above only applies when secrecy is an issue. (And is based on my assumptions as I have never worked in such a place.) If you're a random researcher off some university or research institute, out of money, running low on grants, you know the drill, then the internet is an ideal place to gather data. Code your experiment (obviously this only works with stuff that can run on a computer, actually it doesn't work best with experiments but with survey type research instead). Reach the people who might be willing participants easily. (If you want psi then you could post right here on TKR.) Get lots and lots of people to do your process (be it an experiment or a survey or whatever). If it needs a specialised skill - like psi - you could keep track of scores and have some means of reaching participants in a private message (this can be done anonymously). Then if you need people who are good at the skill you need, you take a look at your top n and send them a message about how they would feel like about giving it a try in the lab. Which might have been the basis of this gotpsi legend, and is a down to earth thing, every researcher would do that. A local researcher has an agreement with a new age type school to screen and gather participants. If that sounds like a pain to do, well you're essentially right. I don't know this about gotpsi offhand but on RPKP there is a notice when you sign up that if your results are promising you might be noticed to take part in further experiments... could be the same thing on gotpsi and frankly, if I would have programmed it myself, there would be. As long as it's voluntary, no problems with consent etc.... I don't see a problem with it. They send you a message - they don't know who you are, a random nickname will do - and it's up to you to reply and get there in person and blow your anonymity if you so desire.
One more thing... if you're a secret organization then you obviously don't want to send unencrypted e-mail to someone with your contact info. Literally anyone can see it. (Especially with WLAN these days...) The phone won't do either - you will want to do it in person.
