1/6 Out of 155 followers, 90+ were bots! Pretty annoying. They're gone now and I have a clean slate to start from. What really shocked me is how easy it was to identify them. Seriously, a few simple heuristics would capture almost 100% of cases. Is this something @XEng can help with? 🧵👇

2/6 For example, by just looking at the usernames e.g. "bO9yMtn63I4Y8kA" and filtering all those with a high percentage of digits, I catch about 50% of cases straight away.

3/6 If I then go a bit deeper, and look at accounts with a Following:Follower ratio of about 50:1 without a single Post or Reply on their account, I'd have caught another ~25%

5/6 Lastly, I dealt with the impersonator type bots i.e. those who had taken a real account and varied the username by a few characters. These are harder to automate and, clearly, they do dupe a lot more people as they had a large number of followers in some cases.
