@TwitterSupport, our developer app has been suspended because of Unsolicited mentions (ref:_00DA0K0A8._5004A1aBXRG:ref) and we've fixed it:
https://github.com/tech-conferences/api.confs.tech/commit/16b029e7592b44f776ceda662196417c4948bbc5 … (I can't reply to the email because the case is closed
)
Can we have our access back? 
cc @twitterdev I guess.
I cannot do anything from the email I received, the case seems to be closed...
