I don't think SE sees the whole Atomos seals/drops thing as an exploit though and here's why:

They changed how it worked once, well after people figured this out and were talking about it openly. They changed the seal acquisition rate to be random through making it so you only ever got the one guaranteed cluster. They did not change the seal exchange rate on any of the drops items, nor did they change the vendor price. They were clearly concerned solely with the consistent seal acquisition rate.

How pissed off would people be if they did some kind of rollback on Monday though? XD Nah, they couldn't at this point. Not after it's been so many days since.
