We do this to keep our community spam-free. If you've been a member of many other online communities, you'll notice they either have (a) more spam or (b) something similar in terms of a moderation period.

I know it's annoying, but we're all volunteers here. We do a lot of work behind the scenes to keep the community safe and running, but it's not always as timely as we would like when it comes to moderating. Sorry about that.

Best,
DocJohn
