if they're lower level and never seem to level up, then maybe. with all the problems of HoD/being locked out/levels resetting, I don't delete regularly. however, if it looks like you're a straight up farmer that doesn't even put any effort into playing and I just hate visiting your town because its a pain in the * to find anything, or the few people that have thousands of primium items to the point that it actually takes a few minutes to load the town or even crashes the game, you're getting dumped.
I think it's more during special events where it's more obvious they're not playing that I'll purge and try to get more active players. he'll, I don't visit every day myself, I don't expect others to.
though come to think of it, hardly anyone visits my town anymore since the last event ended.
