2. Creepy Texts

People often receive creepy texts from strangers. Either they got your contact number through a mutual friend or from some public documents with your info. Creepy messages can be any sweet or stalking kind of stuff. When you receive the same message consistently but in different words, that is creepy.

4. Phishing Texts

Every year, thousands of consumers are affected by phishing scams. It is a new security attack wherein users are tricked into downloading a piece of malware or any virus.

There are also texts on locked accounts and free app coins. Do not follow any of the given instructions or click on unfamiliar hyperlinks. It is good that you delete messages like these when you receive some. But it is best to fight against it by blocking them.

5. Death Threat

The most justifiable reason to block someone is when they start sending death threats. You usually receive these anonymously but it still depends on the case. These are too personal, insensitive, and offensive. The majority of people who receive threats are politicians, artists, businessmen, and others.
