yes, though we do require users to confirm their email, so those may be hired humans and they have working email addresses...
we have had a bit of spam posts in the past, which is why we had to turn on moderation for your first 3 posts, but now that the spam posts have not been going through anymore, our site may be getting filtered out of easy-to-spam site lists. Spam posts have gone down a lot, only a few per week.
Maybe some people just like to read what is going on but they do not have further questions to ask...
