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!

Really fun and addicting

Cubic castles is a game I have played for years now and it’s always fun to play. People who complain about getting scammed on this game have only themselves to blame. I’ve been scammed in the game multiple times and had to restart but those were my mistakes. Cubic castles teaches a lot about how to handle cubits and working for currency. It takes time to get used to the game but it’s worth it. I took a break after losing a couple hundred thousand cubits worth of items on my account. One thing the developers could improve is probably support and moderators. I’ve reported to support and gave a video of me being scammed, name of the scammer, date, time, and realm name but support failed to retrieve my item back. Moderators are very helpful in the game and I understand the stress that’s put on them but sometimes they don’t do their job right. I personally think cubic castles should hire more mods and make sure they have time to be a mod because most moderators are inactive which leaves 1 or 2 mods to deal with everyone. I rated this game ⭐️⭐️⭐️⭐️⭐️ because it’s always been a game I loved and even when I don’t play it, I really miss all the friends I made on it and the community.
