Not the first time this happens. Last time that message showed up in more 2 or 3 mailers. Waited a few days and things were back to normal. No reason to panic I guess
If we are talking about making money, PTCs are good. TEs without Zubees are very difficult to gather money to cashout due to high cashout limits on TEs. For traffic goals I think TEs are better (still, less effective) than PTCs.
TM scam was predictable since their launch. In the middle of their lifetime,a lot of people made lots of $. But in the end it was just another scam site...
