> Wouldn't it be reasonable/acceptable to deny support to those that use expletives when asking for it? People that engage in hostile and harassing emails are the kind of people you won't want to engage at all. This is true for personal communication and also for business. Dealing with that kind of harassment is really draining and handling one person like that won't be the end of it, as there are more such people waiting in the wings to send their expletive filled mouth vomit. The best way to handle these people in business is to ignore them or to outright ban them from your service. Of course, ditching freemium creates a de facto ban on users won't sign on to a paid service, so there is that approach.
