Are there many games out there using TCA (TC+TPM) against cheating?

BTW, is netrek's RSA scheme explained somewhere in simple words,
i.e. not the source code?

Just because you can't avoid misbehaviour altogether you prefer
not to make it harder and therefore rarer at least.
There is never complete safety, you can only make it harder.
Even TCA it isn't impossible to break, just _much_ harder.

Sure, things can spread easily on the net.

How was it different when there have been many _many_ more players
in the past?
I wasn't aware of many intentional cheaters.

So it has to be changed then, _too_.

Understood... but you consider it useless, so you could save the
observer from the possibility of being mislead that it actually is
used the way as described elsewhere.
Given your concern about not wanting to give wrong feelings of
security this would be consistent.
But I forgot... that isn't _really_ your concern.
