For anyone wondering if Threads and Facebook at large will be a fine neighbor in the space and compatible with other apps/services in the fediverse: they’re already automatically hiding comments that mention Pixelfed https://mastodon.social/@dansup/112126250737482807
I’m about 99% sure Threads uses automated spam/abuse filtering based on uncommon words present in posts that have recently been flagged as abusive. Somebody, perhaps several somebodies probably posted “follow my porn account on Pixelfed” or similar that Threads doesn’t like. I’d use something like that if I was making a huge social media thing because you can’t not at that scale.
