I had some trouble last month. They said the feed delivering the ads to my site was uncontactable or some such tosh. When I said "that seems unusual, given that it's displaying your ads right now" they changed their mind. Their technology is... erm... pretty shite.
I applied for TLA on my blogs but couldn't get through the application ... doesn't work with WP (subdomain) sighsss....
Yeah, fine. I just told them they'd made a mistake and if they'd prefer I could remove their code from my sites.
I did nothing on it, and they never give me any alert. Now all my sites are disable. I do not know why.
they concerns pr and alexa rank. they cannot determin the correct alexa rank of a subdomain, so I think the would not apply it. I guees so
