dot.tk domains?  never

some years ago, when I started programming websites, I did a online code generator tool for a social network (using .tk domain)

the site has grown a lot in a short time, received hundreds of visits per day, but one day without explanation dot.tk team suspended the site domain and placed there a page of advertising

after 2/3 weeks, I managed to retrieve the domain, but lost many visitors...

Yeah they did that eveyr month with Omniurl. It was annoying.

Also half of the time dot.tk is slow, so if people don't know your actual URL, they can't access your site.
