I don't like them at although I do have clean brushes available for guests (which I rather hope they don't use!). Each of our toilets has bleached based toilet cleaner by it and it is perfectly possible to remove any offending smears or marks with folded toilet tissue plus cleaner. It can be flushed away afterwards and hands can be (thoroughly) washed.
Not really a scam or fraud, but I wasn't sure where else to put it.
