Don't mind the new users such as "gravity" (created today). They've also created new accounts on Reddit, e.g. the 9 day old whatisgravity Reddit account, spreading lies to try to discourage and scare the Ethereum developers. This all looks like a cynical pump and dump scam, or worse, an attempt to harm Ethereum through cleaving divisions within the community, using social engineering attacks.
If these scammers with their faux aggression and anger had any integrity, they'd post with their real account. I wouldn't be surprised if one or more of these accounts are created by the DAO hacker.
