Since I've had ownership of the site we've fixed all the major bugs, including those from before the move, and unlike other sites, we actually have measures to prevent further spam in the imageboard software. Not to mention our backups are automatically generated every day, unlike before. Half of your laundry list of complaints don't actually refer to anything.
As for a patreon, it became unnecessary when I decided to do most everything myself. the original idea was to use it to pay other people for webdev, but now pretty much all those issues are resolved.
