I've often seen multiple announcements for the
same tournament on this list, and usually there was no
substantial difference in information. My only point is that
I don't think it's possible to come up with a
workable criterion for kicking ads off the group that
doesn't also exclude perfectly innocuous tournament or
question-set announcements. If the ad had been posted every
hour, on the hour, for a week continuously, I'd agree
with you, but as it is, this ad hasn't added a
meaningful percentage to the volume of the group. To me,
that's not a high enough spam level to justify kicking
the ads off.
Cheers,
