casino says my same 6 numbers every spin looked like system play

I just got flagged at an online casino for running the exact same 6 numbers every spin for like 2 hours straight. Got a weird message from support saying it looked like I was using some automated system or advantage play. I get that it probably looked robotic but honestly I just like chasing trends and sticking to numbers I feel good about. I’m not running any scripts or crazy stuff, just a stubborn player who thinks he can spot hot numbers.

Is this normal? Anyone else get heat just for sticking to a set of numbers? Should I mix things up a bit even if I don’t want to, or just push back and tell them it’s my own strategy?
