yeah I would not hold my breath on SE getting this resolved they are actually taking away our past ability to deal with this nonsense via macro its painfully clear that they want these spammers in game I don't even know why they bother making it against the term and condition kind of a joke SE has the same relation with spam then the phone company have with telemarketers...

/flist deny <r>
/blist add <r>

this use to work and you push one macro button and it dealt with everything but they disable the flist deny <r> over a month ago to help out there friends gil spammers
