Question

Web development

I am writing on laravel, An unauthorized user can leave a comment on the site, but how can I make sure that the request is sent by the user who created the comment when the comment is changed by this user?

Answer 1

Authenticate it.

Answer 2

It is better not to accept comments from guests - a lot of spam will have to be filtered. It is better to do only with registration, you can enter through the social. networks add for convenience.
