Coming to Hosting...
Yes you have right, I am really not successfull to find a real hosting...Almost all of I found hosting was scammers / fraud or very poor service...
Therefore I have opened another topic here where about advices about hosting, and would osclass site owners may share their experiences with good hosting providers.
