I run a scraper site and it WAS set up to scan a single bread to automagically find any Q post that didn't contain a tripcode. Same and anybody else just going, find the tripcoded ID and ctrl-f to find the other posts.
I maintain that if Q posts a single time as Q+tripcode and then 5 other times as anon, then he's not anon for the other posts. Everybody can find those posts just by going to the bread. #2707/#2708 is a recent example. My scraper found #2707 automatically, the other sites I think had to add them back in manually. I debated around for about 3 breads this exact point but everybody settled in on the semi-anon rule stated in the bread. All breads are archived anyways so there's that.
