So...yeah....tried deleting all cookies,logging in on e-hentai.org and then going to ex-hentai.org.....still sad panda with the MLP cookie!
I know there are some addons around which modify cookies so you can enter but one addon for one site just slows the browser down ... :\

Hope that helps:

No reason deleting all cookies shouldn't work.

I rarely get punked by the panda. Only if i'm in the middle of translating something when i do my monthly cookie refresh, and stupidly try to go back where i left off.

This. One of the first things I did when I switched laptops was get on Exhentai. Since I had no cookies on the new laptop, all I had to do was log onto g.e-hentai and then go to Exhentai. No panda.

'Error 508 - Resource limit is reached' yeah...We killed that website xD
