What causes toilet spray?

My mysterious problem with toilet spray continues and I am wondering if anyone knows a possible reason that would cause a toilet to spray droplets of water upwards when flushed, sometimes onto the toilet seat, sometimes onto the floor?

People keep telling me it's a problem with the toilet but I have had 3 completely different toilets installed in the last 4 months and I still have the same problem. I live in a condo and I am wondering if there could be a flaw in the plumbing system somewhere. Nobody seems able to solve the mystery as I've even had a couple of professional plumbers come to look. I really have no idea what else I can try? Any ideas at all?

It's the toilet.
There are plenty of toilets that don't spray.

Mythbusters did a piece on that last week to test whether the spray droplets were contaminating toothbrushes in the bathroom area.

Try closing the lid before flushing

What you have there is the poor mans bidet

Just pick up a Toto Drake with CEFIONTECT.
