I never get arrows "stolen" from me because i dont train where theres other people, if you're that bothered use spots other people dont use, there are actually plenty of places to train range without the fear of arrow "stealing", plus if they steal say 30 of your arrows, and most people (well i do) train with steel/iron its not much of a loss, i understand the principal of it all and if someone took some arrows that were mine i'd ask for them back.
