[seven]

ok I found a couple myself
here they are:
other than xlogz and adultblogpress
pimpis.com - this was often down (I tried it a while ago)
rbbloggers.com -offered by real-bucks need to check if they allow other sponsors
x-aff.com -something is wrong with the "create new blog"

enohost.net -looks the only one that actually doesn't have problems (and has fast and great support)

for the moment this is enough for my project, but if anybody knows others please send them

if this works well I will surely use the project on my own hosting
