Do not give money to anyone who posts a BTC/XMR address on this board, and do not go to any onion links you find on this board. You will get scammed if you do.
For links to darknet markets, use dark.fail.
If you want to help Dread get back online, see /r/DreadAlert on reddit for PGP signed donation addresses from HugBunter.
Also treat anyone claiming to be a vendor you know with great caution. If possible, ask for (and then check) PGP signatures.
Fingers crossed that the attacks stop soon and we can all get back to business as usual.
