My first thought was that 5-10 posts a day is just too much. Can't expect everyone to read everything and also react to each one.
Filter lists update only when the extension updates, no fetching up to date lists from servers (this is a big one!)
No custom filters, so no element picker which allows you to point and zap
Many filters are dropped at conversion time due to MV3’s limited filter syntax
No strict-blocked pages
No per-site switches
No dynamic filtering
No importing external lists
