I've got a feeling it would've be a raving review. He's recently posted about having a bad time on Mastodon due to poor interactions he's had with users.

He ends up bringing up an important topic, which is that the "mainstream" platforms all have some level of "celebrity protection" for popular accounts, which filter out negative/hateful replies to your posts. Fedi currently has no such feature, so whether you have 10 followers or 10,000, you will still be inundated with all the garbage replies to your posts since there's no algorithm in place that is grading posts before presenting them to them user.
