Yes it could, and they can subpoena rollitup or imageshack, photobucket to hand over your ip#, then your isp, then your in prison... Was just wondering what you all thought about the risk factor.
I don't think you're entirely correct.
You can view Rollitup.org without registering. But you will not see pics uploaded directly to the messages you're seeing without registering, and I believe there is wording in the terms and conditions to registering which would not allow the DEA to register, and use the pictures you uploaded to your post on rollitup.org against you.
Although, if people are using Photobucket and Imageshack, I believe they are definately at risk.
Regardless, I do not see the DEA wasting time raiding people growing 6 plants or less without some special situation, they're gonna go after the medical clubs that're pulling in crazy profit and the growers that provide for them with large grow operations. (this is what is happening here in CA, they're not even bothering small personal grows that i've ever heard)
