Linksites don't accept subdomain freesites?
 

DD and some other wouldn't accept subdomains on freesites, I'm curious what the reason is, I mean what possible harm can it do?

I've always been doing freesites on subdomains and it just saddens me. Also, can anyone give me feed back on one of my freesites I've had a hard day and I need someone to lift my spirit

Tease - this probably isn't going to help make your day :) but the main reason for not accepting the subdomain sites is that on average, 80% of them are used as a "scamming" method by some overseas WMs, and tend to redirect within a few weeks. To avoid having to go back and remove those links every day, we choose to just not list them.
On the bright side, there are one or two submitters that have emailed WMs of LLs and "arranged" the ability to submit subdomains :)
