So car, OFCOM's "Likely Scam" rules on SMS have flagged 0 of the spam texts I've gotten (not) from AnPost, DHL, or any number of banks. They have flagged a real, non-Irish bank in the EU, a e-bike rental place in France, and a password from an IT provider in Sweeden.
100% false positive, 100% false negative rate.
And in a little over a month, this is going to transition from "Likely Scam" to block, making basically all non-Irish SME EU texts go missing.
