Try to detect and block people opening a second client to .luv/.h8 themselves

[dgw]

Should be pretty simple to do based on hostmask matching.

Possible criteria to use for blocking (in combinations or alone):

• same ident as target (ignoring ~)
• same hostname as target
• nick contains significant portion of target's name
  • more generically, a similar nick based on some sort of string similarity algorithm score
  • yes, this would need research, and probably an additional dependency
• nick has never been seen before (has no rep_ keys stored in the DB)
  • this would be especially useful as a weight factor for other criteria

OP to be updated as I think of ideas.
