Pretty much the reason I've gone to mostly CW and RTTY contesting. For the most part, it takes most of us too long to cuss someone out on CW

and most CW ops are more courtious than to stoop that low anyway although in many DX pileups, I do hear a lot of 'UP' 'UP' and occasionally an 'IDIOT' thrown in the mix.
The saying 'ignore them and they go away' usually works to some extent but there are those diehards that will hang around forever to get the last word in no matter what.
