We are aware of a recent rise in spam accounts, many of which are NSFW. We apologize to those of you who have been impacted. We are taking a number of actions to eliminate this nuisance. We are manually reviewing and removing these accounts as we find them, and are also looking at ways to prevent these accounts from being created. If you notice any suspicious accounts, please send them to firstname.lastname@example.org and we'll take care of it.
