I use piefed which has built-in keyword filters, so there's not really any point sharing them because it's just a list of keywords.

If you want to get the same thing on the lemmy frontend then I used to use a uBO custom filter that looked something like this:

lemmy.dbzer0.com##.post-listing:has(.post-title:has-text(/trump|elon|musk/im))  
lemmy.dbzer0.com##.post-listing:has(.card-text:has-text(/trump|elon|musk/im))  
lemmy.dbzer0.com##.post-listing:has(.card:has-text(/trump|elon|musk/im))  

I changed the hostname to your instance, but I've never tested it there. It might work if the page layout is not too different from the lemmy default.
