Author Buzz has had an influx of spam recently. I am having to manually review a lot of the spammy signups.
It looks like spammers have figured out how to automate Gmail account creation which is letting them by-pass some of the spam prevention filters. Until Google fixes that, there will be spammy accounts that I have to manually check.
If you have any concerns or want to report a spam account please message me or post somewhere suitable.
