The data is usually quite thin:
- flags are rare on most Discourse instances
- suspensions are quite rare on most Discourse instances
- deleted posts may be a sign of forum cleanup more than “this person is bad”, though of the three listed it is probably the most abundant and therefore statistically reliable data point… but that’s not saying much in this company.
We did have something like this on Stack but honestly it was not hugely useful; if you worked on the site long enough you knew who the problem children were without needing to look at data.
