I advised this filter: amount:= new_size / (old_size + 1); action === 'edit' & !contains_any( user_groups, "sysop", "helper", "vstf", "staff", "autoconfirmed" ) & ( amount >= 0 & amount < 0.35) & (article_namespace == 3) & !(user_name in article_recent_contributors) This prevents more than 2/3 of the page removal and cause less false positive than what TortoiseCat5 suggested since someone could write a lot in a talk page and decided to change their mind. I advised not to include redirects as exceptions because redirects are one of the most common vandalism in Fandom, too.
