>>1626643nah, it's just 4chan being weird. Sometimes two pictures on the site gets swapped, probably due to posts being made at the exact same time.
so somewhere in some thread they're now looking at ecchi pics instead of discussing whatever they were discussing.
The best times are when something from a /d/ thread slips through, happened just the other day where a thread on /a/ got a vore pic, that was great.
