well... I will tell you from my experience. after awhile you'll notice he'll start to do a bit of flaming and he likes to poke fun and belittle other people as well.
at first he seems friendly at first. but that's how he draws you in.
second, he fills your head with lies about other members, he did the same to me. this guy will do anything to manipulate you from seeing the truth about him and his group!
If you don't believe me, ask Dark Pulse, Pokemonleaguechamp or pippy, they will give you some insight on bs
hope's this helps
