I have gone through several buildgates to find that at least one of the Trade shop owners did not lock their signs. You guys are gonna get robbed by a random griefer. Again /lock every trade sign. That is all.
You cant really get robbed... but if you put 10k in a sign and someone locks it, that could lead to some issues, so definetly take this advice
With trade signs, it is complex. No one can break them except you (and andrew ), but imagine this: you want diamonds. But you have to get offline, so you make a tradesign and /shout. You put $10,000 in the trade sign to buy 100 diamonds at 100 each. Then someone comes along and locks it, and no one sells you any diamonds D: so you go to break the sign to get your money back, but imagoodbuilder locked it! Now you cant get your money I think you can make a trade sign removal app for this, but I am not sure whether you will get money from this removal
Andrew and wewinagain can remove trade signs, but if someone locks your sign you can put in for a LWC removal and take it down or lock it to yourself. This has happened to me before in my spawn shop. The reason they don't auto lock to your LWC's is they are 2 different plugins for the server
I think trade signs used to auto-lock - or it was all signs, I can't remember - but Andrew made it so that stopped happening. He could technically make it so every lockable thing placed can be locked.. but it would annoy a lot of people. :b
