Seeing this and some of the other people who get spam calls (I get them too from time to time), I am wondering if they allow this legally, why not do something to make the effort of it not worth it? https://www.reddit.com/r/itslenny/ https://www.reddit.com/r/itslenny/ I am reminded of this, where the goal is to waste to telemarketers time as much as possible, and my thought is enough people used it, it would make spam calling not worth it. I would gladly pay for a program in which I could load that up on my phone and have it distract/annoy them back. Thoughts?
