I don't think that any of you guys have anything to worry about, but having unfortunately dealt with law enfor***ent in a very unfortunate way, I think we should all be as careful as possible.
My best friend was a source, and when he got arrested, they grilled him about who every single one of his CLIENTS was... I thought that they pretty much only tried to go higher up the chain, not down... but I was incorrect.
Regardless, when you go to a sources website, go through a proxy. Otherwise they can tell exactly who and where you are. I personally use squid proxies over at http://www.squidproxies.com and I really like the company.
Just food for thought... I think it's a good idea to take safety to a ridiculous level.
