i meant to say that you can talk about ptc sites very few times in your blog,that would not affect your adsense or bidvertiser accounts.

and i don't think blogspot doesn't allow talking about these sites.well they are considered as spam if you just talk about them and nothing else.not only me but you too would have seen many successful blogspot blogs which discuss ptc sites in their blogs.

ok if you don't want to use blogspot,then wordpress is definitely the best choice.but i think you are talking about their free blogs,well thats not a good choice as they totally don't allow any type of money making from blog(read somewhere) and don't allow to use sites like payperpost and kind in your free wordpress blog.

but you can go for paid hosting and get wordpress installed,that would be best of the best and you can do whatever you want to do.
