Major bug!!!

These types of things have been posting to our Facebook,

[{{{site.name}}}] {{poster.name}}
replied to one of your comments/updates/etc.

Or things like,

[{{{site.name}}}] membership request for group “{{group.name}}”
accepted/rejected.

obviously we really don’t want things like this to happen, how do I fix it?
