Did you report the seller? I never had that happen even once and I've done around 25-ish orders almost all from different sellers.
Just like Ebay there are many different sellers, most are legitimate but some aren't. If you see something sketchy just report it and if your item doesn't get delivered you can get your money back.
Aliexpress and Ebay are platforms, just because you encountered one potential scammer doesn't mean the whole site is a scam. That's like saying Everyone on the street is a criminal because you got mugged once.
