Although I'm new to this particular forum my experience with other forums says that blacklists like this always end up in either a silly childish flame war between two people who should really just stay away from each other, or they just get locked by mods pronto, (For good reasons).
Naming and shaming never turns out well.
Best to just accept that unfortunately every online racing game has people who behave badly, race poorly and go online with the full intention of ruining it for others (for some reason they get a kick out of it) and there's not much that can be done about those idiots.
If name and shame threads were used, they would get so long that those interested would be unable to remember every name placed in them and so they become pointless.
Try just sticking to racing with friends and using the old time honoured tradition of trial and error to find who you llike racing with. The best way would be to join a racing clan with a set of rules that every member follows to ensure clean racing.
*Here's the plug* ----- LOL
If you see a lobby with players using UKOG as a prefix to their name you will be guaranteed a good clean race. And when patch V2 comes out I'll be there with them
