While we do like Minecraft: I feel like if you had actually glanced at any of the descriptions for the screenshots we've uploaded, you'd have seen that we run our own server (given that the address is literally on every image).
Sorry if this seems rude, but it would seem to me like anyone who wanted to view your page could do so by clicking your name -- so making a post on someone else's profile with the sole purpose of advertising yourself and your favorite server is... Well... Spam.
I understand that you simply want to be successful - and getting your name and link out there is all part of that: But perhaps you should find a more respectful method of doing so. Posting spam comments on our two day old profile with less than 40 page views is not only offensive, but a bad method of promoting yourself and your site.
I'm not going to flag your comment as spam - but I will leave you with some actual advise that will hopefully be taken to heart:
1) The more content you create, the better. Post videos of your server, screen shots, journal entries, tweet about it, the more the merrier. The more content you produce, the higher the chances are of you being noticed, liked, Favorited, and shared.
2) Consider, on all sites that will allow you the option, basic Search Engine Optimization. I won't get into the exact method of this, but effectively google offers tools that will allow you to see exactly what your target audience is searching for. For example, you might be using the keywords "Free Public Minecraft Server" which has MILLIONS of competitors, but there's a huge chunk of players out there searching for "Public Minecraft server never night no pvp" (just an example). This would allow you to better target your audience.
3) Never - EVER - spam a potential customer.
4) Do your best to promote via backlinking (like you're trying to do) WITHOUT forcing the backlink onto other people. This means that your links should only ever appear on YOUR content. Not someone else's DA Profile, Facebook Wall, etc. This method is respectful to the indidividual, still successful in promoting and cross-linking your site, and doesn't make your method of advertising completely invasive and annoying.
Just some things to consider...
