If you know some big hard guys, use them as long as the help does not require you to pay a physical bill you do not want to pay. If you know a cop, ask him to have a "quiet word". If you know a lawyer, ask them to send a legal letter. You are now in the world of who you know, not what you know, life begins.
Don't get why anyone would send you nasty messages :( you've been really awesome on all the posts I've read. I'm new to this but just keep blocking and reporting it must be easier for you to block than it is for them to create a new account :3
Wow how rude. I am afraid that will happen to me. I try to be polite but some people dont agree with me which is ok. I just hope no one will bully me like they have bullied you. I am so sorry this is happening. I would definitely contact an admin and dont confront the person and do not respond to anything they say.
