I’ve re-enabled comments, including anonymous, here on VT using a groovy post validation plugin called Challenge. The default challenge is a math question (e.g. 6 + 2 * 4) but, er, I’m trying encourage comments, not preparing you for a GED. I replaced it with a simple English question and so far I haven’t gotten a single spam post to the whole site. This is somewhat remarkable considering I used to have 100s of spam comments a week and all kinds of crazy plug-in contraptions that only worked some of the time.
We used to have some cool discussions here, I’m hoping this is all it takes to get that going again.
