Most people have problems controlling how many players can build on their plot, including me, so here is a chapter dedicated to explaining how to prevent griefers.

1. No Mercy.

I know sometimes people beg you so much and spam your chat while promising to give you amazing stuff like fireworks, god armor, and barrier blocks. But please don't listen to them. Sometimes compassion is good, but sometimes in situations like this, it won't help. Some people are kind enough to give you those things for free! Plus people begging like that and groveling - they have a sad life. And if you do that. You have a sad life too.

2. Trust!

Now, I usually only add people I know who will not grief my plot. I can ask around, and see if people think that this person griefs. I can also wait for one or two days before adding them to my plot, as soon as they gained my trust.

3. I don't have time!!

If you are impatient or don't have time, like I said, ask around quickly. People are usually honest unless they they really hate that person, which is pretty unlikely. So even though it may seem dangerous, through my experience, I highly suggest this.

4. Somebody griefed me anyways ;-;

Don't be sad. DON'T CLEAR YOUR PLOT. I nearly cleared my plot, but then a couple of awesome and nice players came to my rescue. They were awesome, and they helped me get away all the lava and rebuild my house! I was really happy. See, not all people are that bad. And soon they became some really nice friends that I had on the internet. I remember I got griefed another time, and I had to demolish a whole building, and some awesome people helped me demolish a whole building XD (don't worry I didn't reveal anything private you people who worry lol)

Anyways, I hope this help you! AND NEVER GIVE UP PEOPLE WHO GET GRIEFED XD
