Thanks for the info! They probably don't have us down in their system as being a UGC site, caught one of our perpetual spammers in the window before we suspended them, and blocklisted us instead of actually, you know, reporting the content to us and seeing whether or not we take action on harmful UGC before assuming that we wouldn't and leaping straight to adding us to the blocklist. It's a pretty common pattern for services like this to block small UGC sites instead of seeing whether or not they're responsive to reports of malicious content and actually act to remove them or not, and it's really annoying (as a small UGC site that is highly responsive to issues of malicious content) when we have to tell people that we have no control over whether or not we're added to lists like that, all we can do is what we do (namely, stay as on top of malicious content posted to the site as we humanly can).
