Chris, I'm as offended as anyone by the multiple identical ads, day after day. But I'm also noticing that the poster doesn't appear to speak English as if a first language. Maybe (just maybe) you've got a communication problem going. You might want to simplify your message:
"multiple times all over the Hubb" is a complex, euphemistic expression. Try instead saying what he/she can do, rather than what is unwelcome.
Hope that helps. Probably irrelevant, I admit.
