Where is the Blocked Words list?

I am writing on behalf of Admins of a Rocket Chat website.
They have to setup an unblock list of words.

But where is the list of blocked words so they simply remove them? Is it in a database somewhere…? Surely there is a default set of ‘naughty words’… some of them are too strong, such as certainy british terms that are not rude at all.

Hope you can help
