This DOS is easy to fix. Just ignore the person.

I find the following things quite easy to do: not replying to random emails, ignoring stuff on irc.

Even better solution: ask to be paid for (non developer-to-developer) support. The best way to prevent DOS is to have a price. Not that it makes interacting with such jerks fun, but at least you get something in return.
