Cryptocurrency spam has declined simply because the cryptocurrency markets have tanked.

Overall spam is way, way worse than before, and it's shockingly low-effort. My DMs are absolutely useless - just chock full of obvious bot accounts who want to "date" me and just need me to click a link first.

I used to get one of those every few months, rare enough that it would surprise me. Since December or so, I've been getting multiple every day.

EDIT: In the one minute it's been since I wrote this comment, I just received yet another.
