I really would like to see such analysis for other Wikipedias where we have a much more limited number of volunteers working to combat spam.
I remember of a WikiMeeting in São Paulo (one of the biggest so far, I think in 2012 when global development folks visited here) where some very commited wikipedians where trying to explain non addicted wikipedians on the importance of removing those spam links added consciously by paid people.
Spam is a real issue and I am afraid it can somehow damage some communities health leaving them overloaded, hence less tolerant to new editors. Maybe when this happen to the English Wikipedia then it will become a real issue.

Ironholds looked at a sample of users with one or more edits to enwiki who were blocked in 2006-2012. The short version: spam is a bigger problem than vandalism or sockpuppetry, and the spam problem is growing.
