Has there been a single documented case of a pilot in us competition putting a tinfoil hat over flarm?

The answer is yes.
I won't out the individual.
It is known that this tactic is becoming more common in europe, including one world champion.
There are also other quite easy ways to kill the out signal while getting the in on antenna 2.

OK. I'll call and raise. Is one pilot doing one questionably useful dumb thing once sufficient to impose cumbersome rules with potential safety consequences, over the expressed preferences of the pilots? Again, worlds is a different issue, as the nature of flying there is totally different.

Is the presence of other possible ways to do stupid things, that nobody has done yet, sufficient? This is how the rule book is starting to look like federal regulations
