Pros and cons

I think cubic castles in an awesome game there are so many things to do and people to meet and it’s just really fun. The downside however is the moderator system the moderators are really bad they don’t really care if you get scammed but if you swear even a tiny bit they get all bent out of shape and yes swearing may not be appropriate for young children but the game does say age twelve and up. A case of a bad mod is someone got scammed and the scammer sold the item that he took and sold it to my brother fairly a day later Nolana approached the scammer who was in my brothers room just hanging out because they were friends (my brother didn’t know he was a scammer at the time) Nolana asked for the item that was scammed but the scammer said he sold it to my brother and my brother sold it right after that so instead of punishing the scammer or asking him for cubits Nolana asked my brother for the cubits that he got for the item to get back to the person who got scammed but my brother said no (justifiably) Nolana kept insisting and eventually threatened him and said that she will ban him for a month if he doesn’t give the cubits. Because my brother didn’t want to get banned he handed the cubits over which eventually ended up being 55,000 cubits which was not fair and this is an example of a retarded mod.

I'm worried

Ok so I still love this game but there's a huge problem I have and I want to ask if there's any advice you can give me or my friends to help me with in this situation.

Ok so there's a few problems so here they are:

1. Random people keep coming to my base and either A stealing or B destroying stuff while I ain't on. Now I have it set up where only trusted ones can build and anyone can visit but somehow they are still able to build so I'm thinking they are hackers and they only seem to strike while I'm not on while my friends are.

2. My friends are getting harassed by people and hackers like breaking stuff and doing other things, I really want to help them out but I don't know what to do, I would buy security locks but I can't.

3. Whenever I place my base in the overworld a padlock appears even though I don't have my base locked so I don't know why and it makes me paranoid.

Those are problems I have and it's making me paranoid and I really don't know what I should do, I really want to help my friends but I don't know how I can help them so if there's any advice you can give me (SonicSmash64) or my friends (friendlylavadude and natalielolipoop775) please let me or them know.

Banned For A Stupid Reason

Today I was mining out a realm of mine and I looked down at my inventory and I saw a black flowered skirt. As I got to the bottom, I thought “Why wouldn’t it be cool if I did a giveaway but with a vending machine”. When I was done mining I set up the vending machine. First, I put down a flower so you’d get things separately, then I put some berries in so you’d have to work your way to the skirt, finally I put down the skirt after a few things. I put glass over it and set it to 1 Cubit. It told me that it was set to 1 Cubit as well! I then did a holla and let the people come in, no one bought anything. I was surprised for a second then I saw people saying it was set for 1000 Cubits. Apparently people reported me before I had the chance to reset the vending machine to the right price. Soon a Moderator came, Moonkitty, or Mooncat, I can’t remember the name. I left the realm and was going to go put some stuff in my chest room when she came in and told me off. She said “you know what you did” and it really ticked me off because I didn’t mean to do it. She kept reporting me until I got 3 warnings and a ban for 1 day. I know 1 day isn’t a big deal, but it definitely is when you didn’t mean to do something!! I’ve had trouble with the Moderators in the past, but nothing like this has ticked me off so much!
