Ok, so let's say 13.6 million people follow DT and know what's going on. Now what's the percentage of people that heard Portnoy left and were just like "oh, damn. wonder what's gonna happen next" and just kinda stopped there.
Alright, now let's assume that the only people that are really going to have a chance to find out and leak the information are in the US. Could probably localize even more specifically around NYC, but I'm not sure how far the paperwork goes.
However, we could probably narrow down people that could leak the information to people that work within the industry.
So that brings it down to fans, in the US, in the industry, probably in the NYC area. That's not a lot of chances.
