If I had a spam texts folder that showed me everything I was being blocked from, I'd both appreciate it and not feel this massive breach of trust that things being sent to me are being completely ignored by a third party system.
The system that does this is absolutely primed for censorship, and we have no way to know it's not being used.
1) Neither the SMS protocol nor any phone I've ever seen has any mechanism to file messages in "folders".
2) Processing SMS messages and delivering them to subscribers has a cost. Doing so for high-volume junk messages would place a significant burden on carriers.
3) Most carriers used to charge subscribers for receiving SMS messages. Some still do! Charging subscribers to receive spam SMS messages would be, quite rightly, called out as inappropriate.
My phone (ROG Phone 3 w/ Android 11) automatically flags spammy texts into a "Spam & Blocked" folder, I assumed this was a stock Android feature - is it not?
Or let me view it through some other means.
I'm not opposed to spam filtration as a user default, but doing so silently without any indication of what is being filtered or ability to verify it is working is not acceptable for such a vital messaging system.
