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.

Read This!!

One day, my sister installed Cubic Castles along with her friend. I asked her what it was and she told me it was kind of like Minecraft but not so blocky. I told her I would give it a try. As soon as I installed it I loved it! I have leveled and now that I know more about the game Im an advanced player. I look back I at when I had started and it gives me memories, good memories. It also gives me a good feeling! (I don't know what it is)... the one thing about this game is.. SCAMMERS! I got scammed plenty of times to know not to trust people. I think the moderators should give them a bit harsher punishment (not to be rude). But other than that.. Keep up the good work Cosmic Cow! -KittyLuvz109

Great On And Off Game But....

So I remember playing this game for a LONG time when it first came out, and I also remember always deleting it and then re-downloading it. It’s very fun and I’d recommended it to many kids (mostly the ages of 7-10) but especially with their parents knowing because I can remember MANY times people on this game got creepy and also many parents don’t know this is an online game. Another thing (and the main reason this game gets a 4 star review from me) is it’s pretty complicated and confusing at first and I think players should have the choice to do a more in depth tutorial.

Overall this game is very fun and deserves nothing less than a 4-star review in my own opinion!
