I agree, it kinda sucks.
I have a DD that I've never seen for sale and have been searching forever and it put me in a tizzy when another anon spilled sauce.
if you want to know but are too lazy to look for yourself, it's more polite to nab the photo and ask for sauce in a different thread. expressing interest in a rare DD, that was unknown until seeing in DD thread, on top of exhibiting I-eat-by-spoon-only behaviour, just gives off such an inconsiderate vibe. like, that bitch is probably going to compete with you if the link is posted.
it's just poor etiquette...
