In plain English
A feature on most apps that stops a specific person from contacting you or seeing your content. Blocking someone is always okay if they are making you uncomfortable.
Why it matters
Blocking is one of the simplest protective steps a child can take when contact becomes unwanted, abusive, or coercive. Many children worry it will cause more conflict, but the block is silent on most platforms. Teaching children that blocking is acceptable, expected, and reversible helps them act early.
What to do
Teens
If a contact is making you uncomfortable, block them. You do not need to explain yourself, and most apps will not tell them you have done it.
