Replying to How to figure out if your friend is trolling?

hey guys,

i have this guy on pinkbike (biking website) who is interested in basically everything i have for sale and a lot of things my friends have for sale. now i believe i know who the kid is, but im trying to figure out if it is actually him or not. he only joined yesterday which makes me suspicious.

Can you somehow check the IP of the account and stuff like that? The name under the registered account is obv a fake.

thanks in advance.
