I had been curious about adult diaper companies and if they knew about ABs and DLs too.
The conclusion I reached is that they certainly would. I went and purchased adult diapers from a well know company, Abena, and I can tell you one thing, they employ very intelligent and highly educated people. Now because of the people they employ, I am certain that they know how to use google. That being the case, if one does a search on google for adult diapers or abriform, gosh there are as many links dedicated to the fetish as there are resellers.
The conclusion is that these companies spend a lot of time and effort researching their customers. They would be well aware of fetishists, but I suspect that they turn a blind eye to it. Why bother pandering to DLs and ABs that occasionally purchase a pack or a carton of diapers when there are institutions like nursing homes and hospitals that buy them by the pallet load?
Any diaper company that was seen to be pandering to the ABDL community would risk marginalising the majority of its customers, the ones that really need diapers. I think that the best that the ABDL community can ever hope for is sympathetic resellers that are happy to supply retail trade.
