I literally run everywhere on my home server with /busy on. The spammers aren't so bad on Legacy servers like Balmung as the sellers can only make toons there at 4 am in the morning. Whereas on Faerie, they create, then spam, delete and create a new character all day long. Blacklisting them is pointless and without filtering tells or /busy, you get a tell from them every 2 minutes or so. It's quite aggravating.
