Guy creeping on me.

So there's this guy who I know creeping on me on Facebook and he keeps calling me the typical lovey dovey names that a SO would use. He keeps saying he's crushing on me and he keeps telling me that he wants to cuddle etc etc.

Anyways, I'm not into this guy at all and it's an absolute huge turn off when guys come onto me like this instead of coming the friend route. Either way, I'm not attracted to him. I've tried playing off what he says without flirting and I've tried ignoring him countless times.

Should I just block and/or unfriend him or what should I say? I'm not fond of feeling "harassed".
