Hey dude,
Couple thoughts:
1) Do not believe these people who say "every time I come across a trap base I roll them to teach them a lesson". They are either lying, not really being 100% truthful of how often they DO NOT roll the base, or in the rare case they are being totally honest the odds of you ever actually being raided by one of them is very very very small. This is a game of statistics and long term view points, you don't design a base that is impossible to be raided, you design a base that more often than not will be successful in defending against the types of raids you will come up against more often than not. In addition, it is not a form of trolling or griefing, its part of the game!
2) Trapping your base is by far the BEST way to get defensive trophies, and protect your loot in the upper leagues. Let me explain why--this is based a bit on the math, and a bit on my experiences (I currently farm in M2). Consider two bases (A and B). Base A is designed to keep the TH in the center/defended/whatever, Base B has a tesla trapped TH on the outside with NO other traps.
Scenario A: IF someone is going to raid you, they will more likely than not get to your TH (or 50%) but in the process of doing so they will also hit a couple of your storages, trigger traps, kill CC troops, kill a hero or two, and probably get your DE also. Massive loss of loot, you probably will not get a defensive win unless they are coming with pure gibarch (even then they can still get the win fairly easily), and you then need to re-arm traps/CC.
Scenario B: IF someone decides to go for your TH, and they see the teslas pop up, they must commit a significant number of troops to killing the TH or they risk losing trophies (which most people in masters do not want to do.) By the time they kill the TH, they have used 10-25% of their available troops just to do so, and the prospect of raiding your storages is very unattractive at this point because they have already netted the trophies + win bonus, and deploying more expensive and longer cook time troops to get another 100k/1k loot is really not worthwhile. You then only lose a very small number of trophies, I would estimate less than 4 based on a quick average I took of my defense log, and get the free shield. I also want to point out that you can design your base so that the vast majority of defenses and walls are arranged so that even with the TH being trapped, and somewhat defended, the real targets in your base (I'm assuming DE/Elixer) can still be heavily defended. Again, are there people who will come across you with a GoWiWi/Lavaloon raid cooked up? Sure, but the vast majority of people who will raid you have GiBarch+some wizards at MOST.
The reason scenario B stands a decent chance of getting you some precious +30 trophy wins in this league is that many people who are sniping TH's tend to do it continually, especially while their main army is cooking. This means from time to time someone is going to go for your TH with 10-15 minions, a scattering of archers, etc. and often times they will not have the muscle necessary to punch through the teslas and get that TH. GG! Laugh at them as you watch the replay! On a side note this exact scenario JUST happened to me as I'm typing this response. HAH!
Anyway, best of luck to you, this strategy has been working for me, and will continue working for me and many others. I've noticed more and more people are trapping their TH's because well, it clearly is a good idea.
