All men ought to sit when they pee

My toilet has the piece of tape above on it, as well as this sticker at near eye-level:

In our other space's toilet, in the social centre we also have a print out taped up. It solely says that it is a sitting only toilet, in both Spanish and English.
The thing is, even with that sticker or tape, I still imagine there are a few men that will likely think "Yeah,.. but that doesn't apply to me! I am neat and can pee perfectly every time!" = Bullshit.
There isn’t a man on earth who, in the morning in his boxers, hasn’t noticed on his own shins that there’s always a bit of piss and water splash-back, there isn't a man in the world that hasn’t realised that sometimes something goes wrong with his own personal plumbing and that it’s simply impossible to take a proper piss and not make a mess. Result: gross toilet seat and floor. Not OK.
And I’ve also explained to one or two persons:
“Listen, I sometimes have 4 or even 10+ guys visiting and of course women, that have no choice but to sit down. My partner & and I are the only ones who have to and will clean up the toilet and any piss is left on the seat or floor; afterwards. I refuse to do that. So, sit down. No exceptions.”
I suspect that about 1 in 15 men still will not sit down, but the advantage of those stickers is that even those men will probably be more careful when peeing, and there’s a better chance that if they do make a mess, they’ll clean it up too.
As for the whole sitting thing: ‘Deutschland ÜBER ALLES!’ ->
