Are girls who give compliments creeps?

I saw some dating coach on YT say that a girl who compliments a guy is a creepy girl.

I came home and saw my super and his son dressed really nicely and I said wow! You guys look great. You should dress like that everyday.

Backstory:

The Dad has made subtle advances towards me that were absolutely not wholesome. I ignored them.

He's married and I get on well with his wife.

I totally have a crush on the son and he's been hot and cold with me but his body language tells me the whole story. I haven't done anything about it. Just chit chat and enjoy the view.

The mom has asked me some weird personal details.

The sister is super unfriendly with me now.

The little ones are always so sweet with me. The youngest boy obviously has a little crush on me but it's harmless.

Anyway, after the compliments that Dad seemed upset and gave me this hard stare. Not an invitation but kinda pissed.

Was I creepy?
