How does spam get past searches and filters? (lemmy.world)

I get a lot of spam. In the subject it might say something about Home Warranty. The sender will say Home Warranty (the actual sender will be randomwords@randomwords.com).

But whenever I use my email's search engine, to delete all emails that say "Home Warranty", it can't find them.

Do people usually just ignore these types of emails?

Without getting too technical, it possible to write letters tbat look english but they are not. Tris technique is used to evade spam filters. Try copying the word directly from email subject and do search

There is a really well known homograph where they say https://www.аррӏе.com/ but the A in Apple is cyrillic not ASCII.

You’d think the server-side spam filters would be set up to catch that. Why mix two alphabets in a URL other than to do something slimy?

Because it all comes in as Unicode.
