https://bitcointalk.org/index.php?topic=1554919.0 for the most of the evidence, mainly the birdmeko, who are the alt of Robertt.
i don't know what just happened to my account and any others, but i was suddenly logged out from bitcoin forum, luckily once i got the access back, i changed it (i am not hacked in fact).
anyway, what happened? a lot of people here seemingly being under control of Robertt! and such accounts even threats the target accounts until they got banned.
any kind of help? more information will be up shortly, i should be safe from Robertt now, i am gonna setup a better password in case of risking hacks.
