I've not spent much time maintaining it since, and I have around 3 active users today.
My current plan is to take the source and db schema and dump it on GitHub, but to get it up + running on your own server(s) isn't easy as it's got quite a complex backend.
However, spammers/bots are still rife on Twitter and I can't help thinking that Twitter clients and/or 3rd party developers who integrate with Twitter could license it from me (to pay for my time maintaining it) and I could further extend it, maybe resulting in less annoying spam.
What do you think?
