Is it offensive that I often change a spammer's alias when I terminate their account or are there other (potential) problems with my doing so?
Someone raised an interesting point that it's a sign of my disrespect for the community as a whole. I maintain that it's only a sign of my disrespect for people who come here, hit us with a barrage of spam, then leave. I wouldn't do it to someone who had already been posting then started spamming.
