Adriana DeVille is a wildly crazy, naughty girl. She gags on cocks, loves it in the ass, screams and moans and swears non stop. She just genuinely seems to love to perform on camera. Can't tell you how many times I've jerked off to her over the years!!

Tori Lane is pretty nasty

Gia Paloma, hands down the filthiest whore who worked porn. Gargling facials, stick multiple cocks wherever you want, physically beat her up, make her cry...doesn't matter just give her her money when the cameras stop rolling.

Sheena Shaw is another nasty one. Seems to really enjoy getting fucked in the ass on camera.

Betty from older german GGG-movies was fucking insane. Did most stuff including piss.

Betty

Tanner Mayes...

Ava Devine gets really loud, talks nasty and just generally goes wild.

Also Gianna Michaels for her bossy attitude, she loves to take control of the scene and order the guys around.

Lisa Anne is a dirty whore, love her.

Ava Devine and Belladonna.Those two will do just about anything when It comes to porn.

I love how dirty Sheena is

for my money it has to be the proxy paige and her ever expanding asshole

Good call on Proxy Paige. I have to throw Adriana Chechik in there and Mandy Muse

Kelly Wells, Poppy Morgan, Sandra Romain.

I so agree with all the above ... wish we could make a compilation from all suggestred whores and arrange a circle jerk.
in my list top craziest pornstars are:
ava devine
belladona
becky from GGG
debi diamond from the 90;s
roxy ray
naughty alysha
sarah jay
puma swede

Don't really like hardcore, so don't know many names. But I never forget Kelly Stafford.
Here's a taste of her work:
