How do i geht rid if all those memes in my feed?

Block the communities hosting them.

1. You limit your feed to the communities you're subscribed to.
2. You block the people posting too much of what you don't want to see
3. You unsubscribe from communities posting too much of that too.
4. You may also block certain keywords.

And Hi, btw

Besides the tips already posted, some apps will keep gifs from looping.

Meme /c's are among the highest traffic groups.

If you're just viewing All traffic on your home instance, you will see tons of memes by default.

On Lemmy's web interface, in your settings:

Top right user-defined pull-down > Settings

On the Settings tab, just past half way down, there's a Type setting, which you can select Subscribed instead of All.

At this point, I also like to change Sort By to New instead of Hot

Press the Save button at the bottom of the Settings tab.

Then when you go to your instance's home page, your default view will be a stream from your subscribed groups.

The bad news is you have to subscribe to enough /c's to populate your feed sufficiently.

On mobile Lemmy apps such as Voyager, there are similar settings.
