Are you trolling OP ? You won't get anything from now , why would you ? If you are selling them because Avatars then Avatars came back to work since sometime if selling them for date of Registration then I don't think it means anything because it won't help you to Rank up unless you posted before which you didn't .. at all .
Sorry, though that acc's with profile pic was worth something
OT: There is no other possbile way to "hack" someone with just their IP All u can do is DDOS or monitor what the user (of the IP) is doing if ur on the same network and that's pretty much it.
sorry, but how do you change a reddit name? never thought that would be possible.
My bad, i though u could do it. (thought i had done it before ;/ ) But the names isn't something like "y0lo89" or something. They are normal looking names
