I wish I could filter for emoji.
I could scrub my inbox entirely of anything involving the damned things as no legit business worth a butterfly fart in a hurricane would ever use them in a professional communication. I could eliminate 99.99% of my junk folder catches by simply deleting anything with one in the Sender or Subject lines. And FFS let me filter on "the same supposed sender or subject line". How many versions of "Confirmation Needed", "Confirmation. Needed", "C0nf1rmat10n Needed" style bullshit does a person have to manually go through, ticking the "This is spam" box on every single one, until Gmail gets the hint? Or the "Sexy(Emoji) Horny(Emoji) F(Emoji)ckbuddy" style senders/subjects? Oh, and *anything* that claims to be from FB or any iteration of the name -- Fuckbook, F@cebook, Faceb00k, etc. I don't have an account so just auto bounce that shit as undeliverable. Better yet, if it came from a Gmail account, kill the account, trace the IP that sent the email, & send a B2B email warning their upstream provider of the spammer.
Or wait for an active connection to that account & send a couple trillion amps back up the line to the person on the other end. Just something to say "Hi". And fry the computer sending the crap. Hopefully it will burst into flames & take out the spammer as well.
Damn my violent fantasies of righteous retribution...
