Need an adult-oriented hosting plan ...
 

Plans from host4porn.com and black.host are attractive for me and I wonder which way is betetr to follow and why?

Anyone looking for a great host, look no further! Exmasters.com adult vps looks great.
We love the speed of the site, the uptime, the support when needed (few and far between), and the features (the automatic backups are wonderful especially).

Take dedicated server

And host what you need.
I recommend contacting the provider and showing your content first.

Accounts from kvchosting.net and planethoster.com are worth trying.
Top notch support, affordable pricing, and I haven't seen a bit of downtime.
