Chatting someone on a dating site but i think they're a bot, how can i be sure before i get invested?

We were a mutual match on POF.

We've had 3 messages. "What's up", "What are you looking for" and then "Can we chat on snapchat??"

The first text was at a semi odd hour, like 6 am.

Her bio also seemed semi normal and the pictures weren't obvious "onlyfans bait"

I dunno, i'm a total rookie to OLD.
