I tend to check when suspiciously bot-looking accounts follow me, just in case they're actually real new accounts, and one pretty funny way I have found to identify the bots is that they all have their following tab visible and they all follow @layzeal as well.
Like. Without exception. Every single bot follow i've gotten in the past few weeks follows both of us.
I don't know why this happens? Clearly these bots are choosing followers based on some algorithm or program and I guess it put us together. Assigned bot buddies. Frequently followed together, do not seperate.
