The problem is specifically with unregulated sites that don't verify the identities of players. The bots aren't so much the problem as the fact that they can collude and share hole cards. But fyi, bots aren't actually good at playing poker outside of specific scenarios vs bad players or in scenarios where the decision tree is not large (ie short stack tournaments where the decisions are pre computed, you can imagine how massive your edge can be when you have a pair of 9s and you know there are already 3 dead aces and your decision is only all in or fold)
