Joke tips can be fun from time to time, but they are something that should be optional, not forced into the players and then told to remove them from the tips.json if they don't like them, that is the upmost lack of respect for the user, no matter how you view it.
There are lots of respectable modders who have tips in their mods to help people understand certain mechanics, and that is what tips should do: help explain game mechanics, how to play or how to achieve x goal.
We can't ask Alex to change the game so that there's a separate "jokes" file that people can enable or disable in the game's settings, nor can we ask modders to have an optional additional downloadable tips.json for those who want the jokes available, BUT here's my suggestion:
Keep jokes to a minimal amount, I'd even say 1 joke per mod, and put the mod's ID as a prefix for all joke strings just as most modders do for all the other tips, that way if some joke is tasteless people can quickly and easily see from which mod it is and act accordingly.
And please, don't come here and say "you can just do a quick search in the mods folder and find the mod yourself", I've heard that one before and once again, upmost disrespect for the user.
