I noticed after HTTPS was enabled by default that there were many fewer spambots on one of the wikis that I monitor for recent changes. Did anyone else noticed a decline in spambots after HTTPS was enabled?

This may be relevant to discussions about the highly active editor stats. While I doubt that spambots and vandals succeed in getting to 100 edits on the larger Wikipedias very often, rollbackers might. Additionally, a reduction in spambots and spambot-related rollbacks might affect the number of new accounts registered and the number of edits per month stats.
