A friend of mine just got out of a rough relationship. Unfortunately it didn't go well as her ex was calling and texting her nonstop to both try and win her back and insult her (I did say it was a rough relationship). After a few days, she just couldn't take it anymore and came to me for help in blocking this guy.
Luckily, I already knew a number of options for blocking people who are being a nuisance, from annoying exes to rude telemarketers who won't take "no" for an answer. Now I'm betting that more people than just my friend occasionally need to block someone who is annoying or even harassing them, so here I'm going to share a few of these options.
First, though, I do want to say that if the person harassing you is threatening you with physical violence, stop reading right now and go straight to the police. They'll probably have you file a restraining order. Once that's done, then come back and learn how to block the person.
Of course, you don't usually have to get law enforcement or the courts involved. The annoying person might just be someone who you gave your number to one time without thinking about it. Here's how to get your peace and quiet back whether you're on a smartphone or an old flip phone.
