The way the “Last Post” is listed, it makes it look like c”v, posters have posted when it’s Y”T for them. That is because the time listed for the last poster does not necessarily match the name of the last poster.
The time is listed for the last post whether or not it was moderated yet, but for the name it lists the name of the last moderated post (or in some cases, the second to last or third to last moderated post).
I understand that the time does not match the poster, but in theory there can be viewers who don’t. It also just bothers me that it looks that way.
Of course, it’s possible that all these posters just made aliya Erev Pesach, or that are in EY for Pesach and hold like the B’aal HaTanya that anyone in EY for YT keeps one day, or they come for all of the Shalosh Regalim and hold by the Poskim who hold that you keep one day in that case.
But if they also posted when it was YT in EY on Erev YT, that wouldn’t work.
