Gday mate I'm sure you are all over the most recent Phishing Scam that is using a copy of your flag comments sent from compromised accounts.
This one comes from the @qustodian account but there are tones of others the difference is every link in the fake leads people to the page intended to steal their account.
These fake @grumpycat comments appear even where there is no bot activity.
Any change you could make a post warning people.
