I think we should blacklist the plz-send-teh-codez (and possibly variations1 thereof). There are not currently any questions tagged as such (anymore), but at least one user (this person) has been actively trying to resurrect it (1, 2, and 3).
All three instances above happened this month. But, I think this tag was intentionally wiped out of existence2, and is now trying to creep back in (which, according to this statement by Jeff Atwood, makes it a possible candidate for blacklisting).
What does everyone think?
2 Based on a comment by a mod on the third post above:
Indeed. That tag used to be pretty common, but we finally got rid of it. Please don't start it again, @chris. – Michael Myers♦ 2 hours ago
Additional Note The tag was common enough at one point to gain a place among the many of meta, which actually states "It is now considered bad practice to apply the tag to a question and users with retagging privileges should remove it as necessary."
