I've posted my finding (about the tracking protection triggering the adblocker-detection) to the official support thread. Art Andrews said he'll pass it on to the developer who is working on the forum software.
It is hard to fix a bug if you don't know what's causing it and can't reproduce it (the "it works for me" problem), so maybe this finding can give them an idea on how to solve the issue. I'm a software dev myself, so I appreciate that it can be difficult.
