Hello Jaroq,

While I am not familiar with either of those hosts here are some criterion I can certainly recommend that you should consider as part of your search process.

1. Does their AUP and TOS openly support and allow for adult content.
2. Do they openly support the adult industry. In the course of your business you will reap the benefits of choosing a host familiar with the industry.
3. How do they handle bandwidth overages? If you are having a great month but they shut you down because of your BW that can cost you a significant portion of your efforts.

Notes:

1. ewerkshost-isp.com There AUP does support adult. The BW with these shared plans seems very limited for an adult site and I would suggest getting more specifics, in writing, on the recourse of high-BW usage. Also there statement regarding domain migrations and allow for 7 to 60 days seems very excessive.

2. extreme-hosting.net This should be a serious concern IMHO: "8.4. Traffic usage All customers who exceed their traffic would have their accounts automatically suspended. A short e-mail reminder notice will be sent when traffic usage reaches 90% and 100% after which the account would be deactivated. Failure to receive this notification would not be considered as a reason for complain. Extreme Hosting is not responsible for any loses users may have because of automatic site deactivation. It is customer's responsibility to monitor regularly his/her site through the control panel."

Hope some of that helps and good luck with your search!
