Comment (by Nao):

 Based on the data @ocean90 shared, I am seeing an opportunity to catch
 unreviewed machine translations using the warning log.
 (the data contains usernames and their activities in detail, so it's not
 appropriate to share the raw version publicly)

 * Between 2020-05-19 21:20:32 and 2020-08-26 10:13:13, there were 13,983
 warnings
 * Among top 20 users with the most warnings, 4 were probably uploading
 unreviewed machine translated files, 2 were well-meaning inexperienced
 users, 1 was a CLPTE, and 13 were very active users submitting lots of
 translations.

 I was easily able to detect the possible offenders by reviewing unfamiliar
 usernames for their translation history profile. They all had submitted
 suggestions for the same plugin or theme in multiple languages. Also, the
 log showed these users' warnings were happening within a short period of
 time (5 to 100's in a row), which is a pattern not typical for legitimate
 translation contributors.

 Types of warnings themselves may not be enough to detect offenders, but
 `mismatching_url` often tend to be intentional.

 I think we should block upload when a set number (let's say 5) of warnings
 are detected in an upload file. At the same time, display a message that
 they should never upload unreviewed machine translation.
