864 xtube.com
866 cam4.com * missing in top100 tubes, ok is a cam
...

It also misses xnxx, hardsextube, beeg... went to check html page source, these seems to miss RTA labeling; redtube also miss from list despite got one RTA tag, could be script timeout there or wrong unicode parsing. Anyway even if fixed this, checking RTA labeling is not enough, as not everyone applies it. Should check meta description for porny words too, and still are we sure this is enough.
