Spawn grief

No. Anarchy is a whole-server rule set. Spawn grief just means spawn is damageable and routinely trashed. Some servers still enforce rules elsewhere while leaving spawn to rot.

Move with a goal: pick a direction and commit until you hit natural terrain, then start gathering. Do not stop to argue with the rubble. If you brought supplies, a water bucket and a few blocks beat most spawn hazards, and a pearl can skip the worst pits. On many servers, getting to any portal and traveling in the Nether is the quickest way out of the destroyed radius.

Yes, but do it like a rendezvous, not a hangout. Share exact coordinates and a simple landmark, and expect to escort newer players out. If there is a /spawn command, assume it drops you back into the mess unless the server maintains a protected pad.

Often. Common ones are hidden lava, pressure plates tied to TNT, cobweb pits, and portals that dump you into kill zones. If a block placement looks pointless in a high-traffic line, treat it as a trap until proven otherwise.

It depends. Some servers never roll back, so layers of damage and builds pile up over time. Others periodically reset spawn or patch a minimal route while still leaving the surrounding area griefable.
