If you don't post, you don't have an account that is used. It's pretty much that easy.
Understand that this is one of the larger boards on the web, and we all volunteer here. Sometimes, we can't help as often as we'd like, either because life intrudes and our time is limited (my girlfriend was hospitalized this week, for instance), or because there's only so much we can offer.
When someone has been assaulted, the best we can advise is that you report the assault and seek out counseling. We can't really counsel someone with something like this ourselves, because in-person counseling is required, and it's particularly difficult when things are iffy (we try not to doubt, but a 13-year-old who doesn't know what police are for, and who lists an incident that would cause injuries which would be truly unlikely to keep hidden is really very questionable).
And the help you asked for here, besides, was with body hair, not with this apparent assault, and you were given that. We can't help you much with the fact that people naturally have body hair, and on men, thick or coarse hair.
So, if you were seeking help with an assault, again, we suggest you report it and seek counseling. Tracking down peope who "picked on you" to seek out "gangsters" isn't very sensible, and if you mean they're one and the same, again, it's very confusing to have this sort of level of fear described and that same level apparently gone to seek them out yourself.
