@dansup I tried it out with Threads and haven't seen anything yet. Maybe its the dot social domain?
@avoidtheories @dansup yeah they probably just domain marked it using their existing spam tools rather than add a whole API check for every link ever sent.
@dansup They wouldn't let me share my BlueSky link either
@dansup The anti-competitor filters went live sometime ago. Meta is trying to avoid an exodus, that Twitter experienced.
@Linux_Is_Awesome @dansup They've always done this. I remember as far back as Google+ and even Tsu they would either block posting outright or nerf the link.
@dansup I've had a pixelfed link in bio for a while, and luckily nothing has happened to it. But I guess if I were to put it there now, they would not allow it.
@dansup@mastodon.social Works fine for me, both Facebook and Threads.
(Is this confirmed by something other than a screenshot from a post? Unfortunately, sharing false information is not the exclusivity of the authoritarians)
@DavidBHimself @dansup
Good question. Might also be an A/B test they're running, where only part of the users experience it, so Meta can test its effect.
@dansup@mastodon.social A small update: the posts got some likes, so they're not even shadow banned. I smell a lie from OP.
@DavidBHimself @dansup It's not a lie, I independently confirmed it yesterday after reading that post.
My post read: "Anyone here use Pixelfed?" Followed by a link to https://pixelfed.social.
Once Facebook pulled up a link card for Pixelfed, I deleted the URL text.
Three seconds later, a full screen error message appeared stating "We removed your post".
I tapped the "See why" button.
It claimed "This post may use misleading links or content to trick people to visit, or stay on, a website."
Tapping "See rule" led to an explanation that the link was (allegedly) spam.
Screenshots below.
Now, maybe they've listed the ban on links to Pixelfed over the past day (I haven't retried it today), but it was definitely being blocked yesterday.
@DavidBHimself @dansup My post is up, too, with no likes--though that's not surprising; I've posted so much left-wing stuff that the algorithm probably prevents almost any of my friends from seeing most of my posts.
One of the huge problems with a secret, ever-changing algorithm is that it's impossible to tell if OP is lying or not. I suspect not, if for no other reason than it's plausible some users or some domains will get blocked and others not. The algorithms are opaque to the point of complete unknowability for us on the outside.
@dansup well that’s surprising…
Funny, because no one was aware that Meta were cunts before they crowbarred ActivityPub into their crappy websites.
@dansup Might be worth checking with the EU regulators. I would be pretty shocked if this did not violate the Digital Markets Act, and that has some fairly beefy financial penalties.
@david_chisnall Most likely "authentically" flagged as "spam" because of so many people suddenly posting links to the same place! 
@dansup so, following melon's example?
@dansup we’ve had 71 boosts and no confirmation. ?
@dansup pretty sure this is also illegal in europe. If not, wanna make it illegal?
@dansup
A friend was ban minutes after saying she was leaving soon and sharing other networks.
@dansup lol how's that extra free speech going
@dansup blocking is rampant and infuriating in most corporate networks; I'm unsure when it became so evident, it's literally like they don't care anymore.
My (then) Twitter account fell through a cliff one day, it was clear as day. Tools didn't report me as shadow banned but my tweets were being hidden, my contacts reached out about it.
It started around the time I started posting about https://moa.party which we kept alive at the time, and https://social.coop.
@dansup if Elon was 20-30% better he would wake up to the fact that it's literally unethical not to allow interop/charge for APIs, and to engage in all kinds of [[shadowbanning]].
@dansup We should make filtering your competition's links illegal and count it as a form of anti-competitive behavior.
hey @dansup, if you like moderation of social networks, switch away from mastodon.social which is too big to moderate and distributor of violence and shit
@dansup building a very nice Streisand effect, aren't they ? 
@dansup I tried this. Posted last night. Checked back this morning, then from a different account in an (I hope) anonymous browser (chromium vs Firefox, to try to further block cookie sharing, etc.).
The link is there. There is no preview of the image, but the link works.
@dansup@mastodon.social
Advantage of smaller fedi instances: often aren't in the legacy platforms' flag lists.
@dansup This is what many predicted with Threads. I don’t block many instances, but threads is definitely one of I think two that I’ve blocked
