Is text-link-ads.com is back?

Few months back i heard that google have banned TLA [ Text-link-ads.com ] was reading this article and found it, and its not good for those websites which use TLA ads, google even ban them.
But i saw google adsense ads of TLA here at DP, and i have checked TLA on google search, they are back and got indexed again.
Google have given them "authority website" ranking as well. so i wanna know that is it safe to use TLA as a Publisher?
Im confused.:confused:
