How to filter paywalled articles from Substack?

[flinesse]

Hi, I came across this FreshRSS thread while looking for ways to filter (block OR mark as read) paid articles from Substack, but noticed that Miniflux does not support content filters on a per-feed basis. What would be the best way to go about achieving something similar with Miniflux?

Thanks!
