He wasn't, Parity is still core tech partner
For the record, this seems a recurring pattern: note that the account is brand-new and the first post on bitcointalk the user makes is to spread FUD about Ambrosus. How it started?
1) a user started offering illegitimate services offering people to send him ETH to get AMB
2) our team warned this user that this is not allowed and warned others not to send ETH
3) this user started spreading false and inaccurate information
4) user banned; multiple new users are created here on bitcointalk and in our chat (whom we ban, as they just start spamming and trying to scam)
There is no need to create fake accounts to blackmouth us. Either use your public, legitimate account to accuse us of any wrongdoing, and we will duly respond, or kindly stop with defamation.
