The problem is that ANY answer to a spam call... Even if it's just hanging the phone immediately after... Makes you MORE likely to keep getting spam called. The best possible action is to ignore it.

As someone who plays TTRPG maybe slightly too much, I can understand hiring a GM (although I'd be afraid they'd be too forgiving). But since I actually prefer GMing, I can save my money.

My suggestions to people who want to try GMing but don't have enough time or aren't too confident yet: Try short pre-written adventure modules (Adventure Path, if Pathfinder). It REALLY simplifies it.
