It depends.

Are they just joining your new wiki to contribute? If they're editing normally, I'd say that's a bit odd, but still fine.

Are they leaving you messages? If they're actively sending you messages, leaving messages about you, vandalising the wiki, reverting your edits, etc., and especially if you've asked them to leave you alone, that would most likely count as harassment.

If you suspect you're being harassed, or they're breaking Terms of Use, then.
