This is a DH Public Service Announcement. XD

Go to your Admin Console and type the following:

ban_set wasteofpages

Hit "execute".

Do the same for these:

ban_set harrypooter
ban_set hpspoilerific
ban_set nowah
ban_set jacjoyce

Apparently these people are commenting with spoilers on unsuspecting journals, so if you fear being spoiled, banning them from commenting is a good option.

If you run an HP community (or a community with a large number of HP fans) and want to prevent them from being spoiled, put this in the Admin Console:

ban_set wasteofpages from communitynamehere
