I've gotten texts and calls in the middle of the night from people wanting help on open source stuff I've worked on, and I have no publicly listed personal phone number. No idea how they all get it, although one told me that he got my business card at a conference. I imagine that's happened once or twice and it's been passed around. I do of course respond by saying it's inappropriate to call me directly in the middle of the night, and they should contact my employer for support or email the appropriate public mailing list and I'd be happy to respond there. Still happens a few times a year, though. Not surprised SQLite folks get overwhelmed, even if they didn't go out of there way to offer. I've worked on lesser-known projects and have never even been the key developer.
