Stay with them if you like but there are a bunch of reliable hosting companies that won't boot you for having adult content. Who you go for depends on what you need.

Mojohost - Everyone mentions this but there are many more!

Vacares

TMD Hosting - I use this one. It's really good on a shared server. The customer service is amazing.

Hawkhost - I could mention many more but I think if you go with any of these you will do good.
