have you guys been called by banks after buying/selling too much over localbitcoins?

Nope, just a 30k tx. (with a smattering of other 5-10k tx's)

Ended up not saying anything as I didn't pick up the call the first time and they never called back again. Account is still active and fine too I guess I'll just keep the amounts low for the time being, although I still don't get why I feel like I'm doing something illegal despite everything being legal. I'll drop by a lawyer and see what he says when I'm free...
