His faction is dead, and he has no means to actively enforce his own rules. His sieging is literally only him shooting at the base in the middle of a night with an SRP cap. Just get two-three people with Corsair IFFs and wipe him out, he'll get what he deserves. Mep has no interest in upkeeping server health - he's just fueling his perpetual OCD for the faction he made back in the days and he's too deep in his own insanity.
