There have been a few (ab)users that received downvotes past 2 months. Mostly those accounts that kept failing to verify (like lindarey) after perpetual requests or those that engaged in abuse like plagiarism, spam, etc.
None of the accounts were blacklisted except re-abusers or those that failed authorship verification.

You seem to have been absent for the last few weeks so you were not up to date with abuse in dbuzz.
