Grief people who have little to no ability to fight back in any way.
SnuggleSnail probably could produce enough materials to siege any base he wants, but he works smarter, not harder.
Exploiting people's natural tendency to help other humans seems to be rather effective strategy,
especially considering lots of people have little to no idea how brutal game HnH can be.Step one: aggro a boar and let it chase you while you run around checking every settlement that seems active.
Step two: if you see a player, drop down to speed two and lie in area chat that you're out of water. If they decide to be a Good Samaritan, proceed to relevant step three. If not, go back to step one.
Step three A: They come out of visitor gate. You will, very least, get to KO and loot the character that came out, possibly killing them.Step three B: They come out of regular (non-airlock) gate. Because you can enter the base without gaining Visitor status, you get to Burn Loot Murder it entirely.Worth noting: this method is presumably a huge timesink, the guy who came out of the non-visitor gate might be the equivalent of Shiny Pokemon appearing. I don't remember why I originally felt the need to specify that in some other post, but it will support the argument that w14 siege was so bad, Snail rather ran around hoping that someone is online and falls for his trick.
EDIT: Sorry if it feels like I've been spamming link to this post excessively. I feel like this is something players should be aware and Jorb should really take into account (
w15 prelude seems it might be a step to the right direction, at least in terms of addressing the previous paragraph.)
