Maybe this would be better suited for r/darknetmarketsnoobs, but I've found there can sometimes be quite a bit of unreliable information there.
I hear a lot of people talk about receiving "love letters" in the mail from customs or the postal service about confiscated items. My question is this: wouldn't confiscated items in the mail be enough for LE to get a search warrant and check phone and computer records, eventually leading to incriminating evidence? Why would they bother sending a notice, why wouldn't they just knock on doors with warrants? Sure, I suppose you have deniability and could say that you have no idea who would send you such things, but I'd guess that 9/10 it isn't some malicious attempt to get someone into legal trouble, just someone ordering something from DNMs
Ain't nobody got time for your small petty 5 pills of whatever it is the fuck your ordering!
