There's a huge difference between simply noticing bots and the due diligence it takes to PROVE an account is botting, and that the account being reported isn't a stolen one.

Unfortunately it's just a losing battle. SE would have to delve into questionably legal territory in order to actually monitor our clients to confirm that people are running botting software, and without doing that they're basically guessing when they shut down an account. Meaning, they're taking back $100's worth of digital content, no refund, based on something they believe you're doing but can't PROVE you're doing.

Banning accounts for botting is complicated because it requires TONS of circumstantial evidence, since they can't legally get any real evidence.
