IMO auto-filter shouldn't be used. Manually filtering ID+ on "obvious" spam. Like:
>Any smut posting
>Convoluted Gematria
>Pictures without exposition or context
>Telegram channels
>Email/Namefag
Generally you see the same exact posts popping up multiple threads in a row, these are spam.
Also, check post count for the ID. The higher the count the more likely they are spam posting.
