Re SQLite, he replied: "@coleifer: there was a sqlite branch, but it doesn't scale well to many-million record sets which is what I have been doing. the design of the software allows drop-in db replacement, it just lacks the code. I can't decide to go back and sqlite or to just make a web front-end."
Comments by some (not all) new accounts are killed by default when they look like possible spam or troll activity. It's not a great solution because it leads to false positives like this one. On the other hand, doing nothing is worse. It's a hard problem, and it certainly doesn't mean that the user is banned.
We're about to release software to let the community unkill these, which we hope will be a much better solution.
