If you're playing in Mobius, then other CMdrs should not attack you. Your Friends list should be exactly that - a list of friends.

It's sad that griefers have perverted the usage of the friends list into a victims list nowadays.
Naming and shaming has bad consequences here just like on the official forums. In the example above, the accused was entirely innocent all along - imagine if everyone started removing the poor commander from their friends lists, blocking him, excluding him from events and shooting him on sight in Open. And then the shitstorm that would ensue because the Mobius admins refused to kick him from the group because there wasn't any evidence of griefing!
Instead, report a griefer to the admins and let them investigate the incident based on the evidence. Usually the difference between an accident/misunderstanding and real griefing are very clear.
