Elon Musk disabled the ability for bots like the one I use on PFA to search and post from Twitter.
Thus, the updates people could post during WSOP events with PFA-related hashtags will no longer work here. That's why you're not seeing any.
Sad to see this go, but I guess Elon is trying to recoup some of his $44 billion investment. In order to get this functionality, I would have to pay $100/month AND redesign the whole bot to their new standards. Not worth it.
If I'm bored, maybe I will manually post my tweets in each thread so you can see how my various events went, but no promises.
