To be clear, the crawler wouldn’t access any private data at all. It wouldn’t even be logged in, much less have any sort of special permission. It’s just looking at the topics lists that any other person or bot could see, malicious or otherwise — I’m sure far worse have already tried, and we’re already all in AI training sets, for better or worse =/
But, still… I made a similar, presumptuous (and arrogant, yeesh, I was such an ass back then 
) dismissal when I was younger here: A browser addon that embeds SDMB user portraits into threads?
I won’t make that mistake again. People can get nervous about their privacy, so if there’s a concern about it, probably better to just respect them.
Besides… it’s all about quality, not quantity, right?
