Agreed with venturefox. If you're planning to get consistent visitors and more importantly returning visitors to your site then avoid these free stuff. When I find a site I look at the domain name, alexa ranking, design etc to trust. First good impression is very important. Cheap domain will usually mean cheap content to me and I really hate bad designs.
its happened to my dot com site also (online shop), until now its still blocked by facebook, and alexa rank also become (zero) i never did spammed on facebook but yess google detect my dot com site and it categorized did phissing activity...( paypal.com.fr.cgi.bin.webscr.cmd.login.run.dispatch.mysite.com) and nouvelle.securite.avance.paypal.mysite.com <<< its like subdomain crated by hacker..but know i already clean all database, change cpanel pas and delete those subdomain...the block still exixst... what shoul i do?
2 Solutions: 1.) get an SSL cert and use the https version. 2.) buy a new domain and redirect it via .htaccess to banned domain. Both work! Don't bother contacting Facebook.
Recently facebook has had some bug of the system which has blocked not only business pages but also ordinary people's profiles which have been existing for a long time.
You can try and contact them but the reality is that you probably will not be able to get it unblocked.
