Has wikia changed the rule that prevents people from editing some wikis without accounts? I am a regular user at Powerlisting.wikia.com (Superpower wiki) which due to its very nature might attract underage users and you needed an account to edit stuff. But in the past week or so I have noticed you can edit as an anonymous (your IP address shows instead of account name) user again, which is absolutely terrible because the level of spam, vandalism and clearly underage children has increased to barely managable levels already.
Spam was unheard of on this site when you needed to create an account. My question is can we admins activate an age/login barrier to prevent this vandalism continuing? Some of us actually do need it.
