How to directly contact an administrator about a poster who trolls Michael Fassbender's message board.

There is some issue occurring on Michael Fassbender's Mesaage Board. A poster on there you know to insult every poster on there with racial slurs and offensive , rude comments have overtaken the board. This poster has caused so much tension on there , it's starting to make me lose interest with IMDb. I do have the poster on ignore and so does the majority of the regular posters on there, but that poster will still follow me around replying to posts from other boards I have visited. And although I have him or her on ignore this still isn't stop other posters from reading what they've written and conjoin them in cyber bullying. I've been a member of IMDb for so long and I've never encountered or experienced such a behavior as that poster's. They are ruining the board and I know Administrators know who it is just by reading their IBR. And I can also provide proof that the poster that causing this tension is indeed the same person. They've also sent me a very disturbing pm calling me racial slurs and derogatory names. Which is why I have them on ignore but they're constantly following me around different boards and others. All this is occurring on Michael Fassbender's board please assist us. Please help. This poster is doing this all for fun, it is becoming annoying and frustrating. Please block this poster LenaAFoster also known Gorilla Hunter and Invincibelle and corpse in a box. It is the same person and I can prove it. Please do something about this.
