Cash game bumhunt rule?

so i’ve been told by some regs at my local game that “bumhunting” is frowned on and kinda against the spirit, but i’m still confused about what folks think is actually crossing the line. is it just when you hop from table to table looking for fish, or does it count even if you just keep rebuying at the same table when weaker players sit down? honestly i don’t wanna be that guy nobody wants to play with, but if you’re grinding to win, isn’t picking your spot sorta just how it works?

people always say there’s some “unwritten rule” about it, but no one seems to agree on where to draw the line. in blackjack it’s all about maximizing your edge and not worrying about feelings, so i find it weird that in poker there’s almost this moral layer over what’s really just playing smart. like, is everyone just pretending not to care or do some of you actually take this stuff personal? i always thought if the casino lets you pick your seat, you just pick the best one.
