This spam trap, unlike most of them, require that spammers keep an
additional piece of information around in addition to the e-mail address,
information that they cannot construct mechanically (provided that you
construct the regex carefully and different people use MTAs with different
message ID construction patterns, the latter generally being the case).
That's a *huge* loss for the spammers; unless tons of people start doing
this (and even in that case), they just can't handle that complexity.
