I do get it. I've been on here 7 years and seen & been involved in my share of drama and bullying trust me. Not only on here but several other sites. But I ain't letting those types of people ruin something I enjoy. And all you need to do Is block anyone harassing you. It stops them from sending messages, or viewing your posts etc at all.
Its not like they can make multiple accounts and continue to harass you. You get 2 on here period. Have you spoken to Jelly as well? She is usually good with sorting that stuff out.

Unfortunately it sounds like you've made up your mind anyway. So nothing we say or do is going to change your mind.
