Maybe you should explain to these people why they are hurting their fish. And be a good friend, and buy them a small bottle of declorinater for their fish. Also, give them a link to the website and highly suggest that they look into some more tips on betta keeping.
If I got many emails from random people about being a bad fish keeper, well, I'd. crap a brick. Sorry, but true. I think there is a good way to going about this, but the way your suggesting doesn't seem like the best approach, sorry. But you are doing it for the right reason, good job :)
