Here you posted a message implying you control the Twitter account @kevinguillem. It's possible the hacker got that account too so it's probable not enough to recover the account but if you prove you control that account then I'll leave a negative feedback on Skatebird, at least until more information is provided. You can just tweet something like "This is Sk8tebird at bitcointalk" or similar; or DM my account @ecuamobi if you prefer, I'm temporarily following you.

A negative feedback can at least make the hacked account useless and force/encourage the hacker to give it back, as it has happened before.
