what is tk?
.tk is a free kind of domain name. So it means it can be a prank; it can be a experimental project/site. Be careful while going through any .tk domain. I am not saying that these are all frauds; as I am also a former user of .tk and it was really a help for me to have a free domain name to start my blog. I continued almost 1.5 years with the .tk domain name.
