This subforum has to do with any issues regarding the network, not with something like a supposed gang conflict.
If you want to hear from someone with more authority on this matter, PM either docrikowski or gamesguru as they're both the led-bys of the gangs section, so they'll be able to answer your question.
With that said, however, I don't really think this guy can stop you from making your gang. I'm pretty sure the admins have better things to do than shut down an e-gang. As well, it's not like he owns the rights to the name The Lost.
