Can I join a Minecraft Vanilla Private Server?

My Application-
Age: 14

YouTube: (if needed) 123seemystuff

What I can do: I'm pretty much just really good at minecraft. I'm good at building, if I take my time. I mostly mine, so I'll always have resource. I very rarely die, only if I just don't care at the time.

I can say I want a server with at least either my age, or at least some fairly mature people.

Looking for a Minecraft Server Hosting for Mo' Creatures?

Hi! I was wondering if anyone had any suggestions for a Minecraft Server Hosting for the Mo' Creatures mod. I'm not very good with trying to put mods onto servers so I would really appreciate some help with finding a hoster I can play DrZhark's Mo' Creatures Mod with my friend.
I'm only expecting to play with one other person.
I don't want to pay more than $10-15 if possible.

What is wrong with my mineshafter?

I use mineshafter instead of the real minecraft and I seem to be the only one with this problem. My friend also has mineshafter and this doesn't happen to her and I'm so confused. Once I login to my account and start the game in singleplayer, it loads the world and shows the blocks but after 2 seconds, they disappear and all I could see are chests, mobs, water, lava, and people… This also happens in multiplayer when I play on servers but it doesn't do that after 2 seconds. It just randomly does this weird glitch while I'm playing. It's so weird! The last server I played on with my friend, I explained it to another person and that person thought that I was hacking and using some hacking system that allows that player to see mobs and blocks, but in fact I wasn't and I had no idea what that person was talking about! All I really did was directly download it from that site and update my Java, but it won't go away and I can't find anything else similar on the web to my problem! Please, anyone, help?What is wrong with my mineshafter
