I don't see anything wrong with it. Seeing how strong of a reaction it gets I'm thinking it could be a viable strategy just to get a tilting fish to follow you to another table.
I've noticed midstakes HU regs do something similar. They would go play lowstakes FR and just donk around in the worst way possible in the hopes that someone would look them up and follow them to their HU table.
All is fair in love and war. Don't judge, be nice, seek happiness.
