A toilet that is installed improperly and is on unlevell ground and wobbles or if the screws get even a little loose and the toilet wobbles every time you sit down, then it will end up with the leaky wax seal.
I agree this is not really “willy nilly”, There is a clear sign of something wrong with the wobble. But a lot of people just aren’t taught this stuff throughout their lives so they don’t know that that’s a problem. So then you end up with people sitting on a wobbly toilet for years and then the wax seal moves and starts to leak.
Uncaulked is the way to go. If you do maintenance and keep everything around it clean. At least where I’m currently living in the U.S. that seems to be the standard. I have seen other countries where the toilet and shower are all together and they just shower and spray down next to the toilet. I don’t know about caulking there.
I have also seen the caulk around that leave the back open as well. That probably also works. Check code is most important, but I personally prefer no caulk look







Maybe someone here can advise. I ran two of the available “checking” scripts to see if I have any packages installed. Both came up with 1 package I have installed. It is gtkimageview, which is on the list.
However, if I look through the pacman.log I see it was installed on 2024-10 and last upgraded 2025-01. It seems to me that suggests I installed it before this all started, so I’m probably not infected?
