No, social media is not just for pictures.

But if someone is using it just for pictures and you try to sell them on a service that isn’t fitting to their use case, that’s on you if they’re not interested.

Know your audience. Offer them alternatives that actually fit their preferences, not yours.

Oooh they were talking about Image filters…

My brain defaulted to keyword filters etc

Wait how do I use the cat filter

There’s a keyword filter and an NSFW filter

Not sure the problem is your sister, as much as it is your conflating the fediverse with Lemmy. As others have mentioned, the appropriate response here seems to be a link to Pixelfed rather than frustration at someone using social media differently than you. You wouldn’t try to force an IG user to join Reddit if that’s not their thing.

You can block communities and instances. This place would be intolerable without that filter.

I didn’t expect to see my boi Thurston today. RIP you crazy son of cat.

It has a nice filter where it excludes people that roll their eyes when they hear words like “federation”.
