Well, since I'm not a noob, I'll tell you what griefing is - and this is a violation of TOS. LL refuses to do anything.
Whenever I cannot conduct business in world - that is griefing. So, this is not a dispute between residents. It is a form of economic terrorism.
And just like real life, TPTB refuse to deal with the underlying issue. If you don't agree, go inworld, and pay a visit to the Homerlone sim and see for yourself. Then file your umpteenth abuse report and get ignored. Pfft. Why do we pay for premium accounts in the first place?
