A more thorough explanation:

Definition: A libeler is someone who writes and publishes a statement that harms someone's reputation.

For example, if someone writes an article accusing a politician of corruption without any evidence, they could be considered a libeler. Another example is if someone posts false information about a celebrity on social media, damaging their reputation.

These examples illustrate the definition because in both cases, the libeler is publishing a statement that is defamatory and harmful to someone's reputation. It's important to be careful with what we write and publish, as it can have serious consequences for others.
