You should Research the author

Hello :)

If you don't know if an author is credible, you should research them.

Researching the author would help you to find more information on them, which would give you further insight on whether or not their information is reliable. This would be better than disregarding the author altogether if it were the case that this were a credible author.

Hope this helps and have a great day!
