it's super gross the amount of stealing that happens in ac, especially when you remember that it's basically a childrens' game, and a lot of children do play it. which means they probably get their things stolen too.
but yeah, i've only had a few bad experiences. the first one was my fault for being dumb and trusting people ofc. the first week the game was released i got the midna mask. i was super pumped bc yo midnas my favorite and boy that was fast. so i was wearing it on the island. everything was going great, i talked to some people, caught a lot of bugs. and then some guy came on and we were the only ones on the island. he asked if he could try on the mask and even though i knew it was a bad idea, i took it off and dropped it. he put it on and i was sorta like "yeah cool ok give it back" so he took it off. and then played in his inventory for like 5 minutes before saying "oh, it's not there anymore?" for 1. what a bad lie. for 2. rude. i blocked him but i didn't even think to flip the switch so i was down a midna mask for several months.
then someone on this site added me and i thought yeah its fine they just want friends. they also added me on skype which i'm also ok with or i wouldn't have it on my profile. well i was having someone over for a trade, and i normally don't close the gate after they enter because
everyone asks if they can come over. this person didn't. so i had two people in my town and i didn't know what one of them was doing. i didn't want to end the session because the person i was trading with was on a busy schedule, so i told the uninvited to stay by the train station until we were done. she didn't. she
ran off. i have a sign right by the train saying "don't run and stay on the paths" it's the first thing you see. she ran off and through the grass. so i had to hunt her down after the person left and ask why she was there. she also made a note on my bulletin complaining about how "everyone always treats me like a criminal i'm not a thief" which is another thing i appreciate people not doing; clogging the bulletin. but she ran around talking to villagers and everything i don't like strangers doing. then when i got her out i found out that wow incredible, there were flowers missing. what a shock.
she told me that she would've asked if she could come over but "i didn't have a way to contact you" i was on tbt. we were both on skype. she could've asked at any time. that was also the last time she ever interacted with me. i deleted her because we never talk or anything but seriously. if you don't want to be considered a criminal, don't go to someone's town uninvited. don't run away without their permission. literally don't do anything the person doesn't say you can do holy heck.
and i have of course had a few people on the island that just sit in their inventory so that you can't leave. it was only annoying when i had to flip the switch and lose the muu muu
