Matt this site Netflix is run by dweebs with no clue or care about DOS or insane spam flooding
they are clueless.
on our sites (not here) we block by IP, any spammer.
we even block who regions of China and Ukraine.
or all of IRAN, they are the hackers like no other, for decades.
or block a whole IP range we do, if they have 100s of spammers in local zone we block them dead, 100%
also we run pro grade, blacklist engines, paid, this get rid of 99%
just so you know, that is what I do.

I guess PANTS is "Rubbish" or more accurate dirty diapers?
the correct phrase is spam floods suck.
