Unlike some people who don't bother to READ before they post their OPINION,I see you say you have a town bell already,this is great as long as you can afford the the upkeep. most of what is suggested is sound based on individual play styles (and that's really what it comes down to).Personally I only disagree on a couple points:
*multiple walls- really only need a couple layers,and no "Honeycomb" design,as it won't add much of deterrent to someone who's pondering coming through a wall despite defenses anyway,you'd have to make the "cells" really wide or else wall splash damage will mean all you're doing is wasting valuable real estate you could be building on. just layer your walls with WEAKEST outside,as (unless they changed the mechanic and didnt announce it) walls only splash same or weaker strength walls,i.e. split-rail only splashes split-rail and makeshift,stone hedge only splashes stone hedge,split,and makeshift,etc.
*wall far out to keep actual base from being seen - again,this is kind of a fruitless (and expensive) effort in my opinion,in fact likely to do more harm than good,as again,someone who might actually be able and willing to risk a high bile character against your defenses (the ones we're worried about,right?) is going to see that and ask themselves "what is he/she/they trying so hard to hide??" Stick instead to making your base exterior looks as junky/newbie as possible,as the same aforementioned character is likely to assume there's nothing you have remotely worth risking their crime/combat alt they've been grinding for months,and will go away and look for wandering defenseless newbs to pick on
*using the same trick with appearances,you might want to consider a "bank" alt,one that isnt really "active" and kins NOONE (save maybe other alts,your choice) with a small claim and lean-to, just to hold your valuables. build a single modest fence and several Torchposts,and then this just looks like a very cautious/defensive newb. Of course it isn't foolproof,but again,most are unlikely to risk ruining a hard-grinded character for the "high" likelihood of getting a priests robes,flint axe,and common forageables for their trouble. :p
*with a tclaim (bell) noone can even TRY until they drop a Trial By Fire nearby (and properly aimed) and wait 24 hours for it to "take effect" so watch out for these!!! keep a high phlegm alt in the town (good anyways,for mundane chores) with the Waste skill and if someone tries Tbf keep checking on it and trying to bash it as a few hours before its effect activates it becomes vulnerable. I've not had the misfortune to deal with this first hand so if someone else could chime in about whether or not a pclaim over the Tbf can be necessary/helpful,that'd be great. otherwise,couldnt hurt, 150s to potentially save your town is a pittance..
*work WITH your villagers - the theory is that you're stronger as a group than individually,find out who plays at what times and try to make sure there is someone "keeping an eye on things" virtually round the clock. sometimes the best deterrent is an active character of unknown bile strength running around the claim. insist your people notify if theyre going to be absent for more than a day or two,and kick inactives aggressively.
As with everything I post here this will subsequently be argued/bashed/etc. I dont care but I will state that these are MY opinions,there are MANY different strategies and play styles and there is no RIGHT way,regardless of assertions to the contrary. Ultimately you find what works and feels right for you,and go with that,only time and experience will tell you if you should change things,and how. hope this helps give you ideas.
This game is full of cowards. Don't fear the braggarts and blowhards,it's the ones who CLAIM to be your friends that will lure you into ambush and backstab you.....
