Ah, sorry to bother you.
But In all likleyhood, it wasn't the original co-founder.
You probably had you admin setting set to automatically accept new co-founder ( something that is by default, so not many people know that). Because of that, a very specefic hacker ( often called Mikey) got into and did what he did.
You are not the only one.Several group have been targeted, other have been wiped.
That idiot is only doing it because he likes the attention ( trust me I DO know a lot about this guy).
What you do now is your choice, of course.If you need assistance, theNoMorehacker group could help.
( And i know some say you think it,s DemonDragon66, it,s not him, he's also a key memeber in the nomorehacker group)
