I got tired of SMS spam from political campaigns. I found an app called Bouncer for iOS which lets you create your own filtering rules to move SMS into a junk folder, but that seemed like hard work.

So I tried various paid services that claimed they could stop SMS spam, some of which claimed they used AI. None of them worked as well as Bouncer plus a few rules I wrote myself.

Kotlin pipeline example

Example of a processing pipeline in Kotlin, implemented two different ways:

1. Using JVM threads and BlockingQueue (package threads)
2. Using Kotlin coroutines and channels (package coroutines)

The pipeline in both cases goes Source -> Filter -> Output, with all three stages containing blocking code.
