Some more detail: https://it.wikipedia.org/wiki/Speciale:FiltroAntiAbusi/7 sometimes start catching edits from autoconfirmed (I once added a redudant clause for bots, which obviously didn't solve anything). Here's an example: https://it.wikipedia.org/w/index.php?title=Speciale:FiltroAntiAbusi/examine/201858102&testfilter=%28article_namespace+%3D%3D+0%29+%26+%28%21%28%22autoconfirmed%22+in+user_groups%29+%7C+%28user_editcount+%3C+20%29%7C%21%28%22bot%22+in+user_groups%29%29+%26+%0A%21%28user_name+in+article_recent_contributors%29+%26+%0A%28old_size+%3E+0%29+%26+%21%28%22%7B%7Bcoord%22+in+added_lines%29+%26%0A%28rcount%28%22http%5Bs%5D%3F%3A%2F%2F%22%2C+string%28added_links%29%29+%3E+rcount%28%22http%5Bs%5D%3F%3A%2F%2F%22%2C+string%28removed_links%29%29%29+%26%0A%21%28count%28%22%3Cref%22%2C+string%28added_lines%29%29+%3E+count%28%22%3Cref%22%2C++string%28removed_lines%29%29%29%0A though the edit was caught https://it.wikipedia.org/wiki/Speciale:RegistroAbusi?wpSearchUser=Azazello%26margherita&wpSearchTitle=Alan+Marshal&wpSearchFilter=7&wpSearchEntries=0

For what it's worth, I've had a dig through the filter (filter rules look okay), and I've confirmed this appears to only be happening on it.wiki (not noticed any random false positives on en.wiki yet)
