Many moderation tools relied on the Pushshift API; Reddit cut their access off earlier this year. Pushshift will supposedly be restored (https://www.reddit.com/r/pushshift/comments/13w6j20/advancin...), but access must be approved by Reddit and is only open to mods with a Pushshift account; there are also additional usage restrictions. IMO it's an open question whether Pushshift or most of the services using it will ever be restored. Pushshift is now owned and managed by NCRI (Network Contagion Research Institute), which is based around selling the data to intelligence agencies (https://networkcontagion.us/technology/). Access for moderation tools isn't really part of their business model.

An additional factor is that the third-party app cutoff cost Reddit a lot of goodwill. Some bot developers such as u/Blank-Cheque have already taken their bots down. My other comment (https://news.ycombinator.com/item?id=36343447) lists some of the affected bots.
