I know of the categories, but the problem is that they do not seem to be
comprehensive. I can estimate, based on them, that there are at least
150k or so editors who were banned for vandalism, but it seems many
vandals do not make it into those categories, suggesting this number is
underestimated.
Still, we should be able to get some estimates. We know, for example,
that something like 5 or 6 million of accounts have made 1+ edit on
English Wikipedia. How many of them were indefinitely blocked? This
should give us some idea.
Alternatively, we know how many accounts make an edit to Wikipedia every
given timeframe. About 100,000-120,000 editors make at least one edit to
Wikipedia each month. If we knew how many are indef blocked in that
period, that would be another useful estimate.
