I just trashed a 270-word gibberish spam comment that was liberally sprinkled with the word 'marijuana' and contained a single link.
It came out of 68.169.32.0/20 (WestHost Inc., Providence, UT) with the UA:
"Opera/9.80 (Windows NT 6.1; WOW64; U; Edition Ukraine Local; ru) Presto/2.10.229 Version/11.64"
Edition Ukraine Local?
