I'm gonna get flak for this but no, Discord does not sell any user data, no matter how many times people keep repeating it. Quoting a legendary redditor here:

Discord's privacy policy repeatedly states that they do not sell your personal information:

We don’t sell your personal information. Our business is based on subscriptions and paid products, not from selling your personal information to third parties.

We make money from paid subscriptions and the sale of digital (and sometimes physical) goods, not from selling your personal information to third parties.

We do not sell the personal data of our users or share personal data for targeted advertising purposes.

‍No sale or “share” of personal information: The CCPA sets forth certain obligations for businesses that sell or “share” personal information. We do not sell or share the personal information of our users as defined in the CCPA.

This is a legal document that they will get in trouble for if they were lying. They've already been fined hundreds of thousands of euros for GDPR violations but that curiously did not include a fine for "took people's personal information and then sold them without consent whilst explicitly saying they didn't do that"

Discord further has no third party advertisements which they can use to "sell" your data by allowing those advertisements to target you.

Yeah it's great. I can spot RPS headlines with ease considering how much obscurity they put in, in comparison. It can be someone's cup of tea though. I like my headlines factual and conversational!

Now this is a headline!

Provided the community has clear rules on where to post gifs/memes redirecting the user is fine. Of course it should be a gentle reminder and not feel as if the user is getting berated.

If they still get pissy after that, it's more on the user. A reminder to follow the rules is not a personal attack.

So just scroll up? It's not like when a message is off the screen, it's gone forever. Or do you never catch up on messages that you missed while offline and just go in from there?

The good thing is that you can choose to ignore the meme, reply to the interesting thought and continue the conversation. Then if you keep the conversation going, it could be made a thread if people are interested in it.

Also a honeypot for memes is helpful so people are less inclined to drop them in general channels
