I have blocked all the sublemmys that are doing it

Be real careful calling out or reporting a bot/troll. Some weak ass mods around that will ban you for either even though they say to report the mod...

You must might want to check out !fediverse_vs_disinfo@lemmy.dbzer0.com. I started it recently to help people identify and report disinformation on the platform.

Thunder, the app I use on android, has a keyword filter so I don't see that junk.

Edit: I keep informed via rss. Lemmy is for fun so politics get filtered.

Its election season boyos. You cant escape it, even in your fediverse hidey hole.

Consider using one of the Lemmy apps that supports key word filters.

Filter out the names of the parties and vice/prez hopefuls and you'll cut 90% of it from your feed.

Blocking communities you're not interested in is also helpful if you visit All. It's an uphill battle - I've blocked over 600 (sports and yiff porn probably account for 500 of those... jfc...) and still need to do some pruning, but my All is pretty personalized now.

I thought it has always been like that?

Lemmy APIs are free of charge, so spamming stuff here makes sense from a financial viewpoint. It also makes it trivial to ingest the data for GenAI use.

It's more of a permanent flooding situation, but, well, election year. I just block shit that gets to be a nuisance - some instances are entirely devoted to shrill screeching, some have legitimately decent communities that just aren't worth the astroturfing/doomposting/negativity/politics/malicious management/people being twats or 100 other reasons. None of it's missed, except it shows how much of a ghost town this is when you remove the ragebait.

I lost my (several pages long) blocklist in the kbin.run disappearance, Lemmy actually having instance blocking does a lot to make it easier to build back up. I do wish blocking an instance also blocked its users, which doesn't seem like the case.

If you only look at your subscribed communities you'll see much less of it.

Since Lemmy is an open source platform it is incredibly easy to build automated bots to spam it. I suggest looking for quality user Profiles to follow, and see what communities they posted on to find high quality communities.
