Nope, none. I have an incredibly long written list of small and large software developments planned for Teensy. Gaming the spammers just isn't anywhere on my list.
Ideally, some of these developments will help sell more Teensys. I'd much rather focus on that, and if necessary, use some of the money to simply upgrade the server to insanely overkill specs if this becomes a problem again. It's actually relatively cheap to get a pretty amazing dedicated server these days.
