TL;DR
Trash scanlations has picked up a large number of series.
Trash pushes their patreon page and constantly ask for donations.
Trash pressures rival groups to drop their series when there is questionable ownership.
Edit: Looks like there's no doubt anymore, Trash has some sketchy things going on. Look at this, https://mangadex.org/chapter/457768/1 post. I can confirm that discord post is real. I saw it earlier, but didn't bother to check it out. Join the Trash discord and look under announcements to see for yourself.
