Well, with the forums it's always best not to be too brash and assertive, especially when you're new to them. Get to know this place and its community a little. See what topics are acceptable, which ones have been done to death, and which ones tend to thrive. The mods will close threads that are redundant, lack content, or which they know from experience will just crash and burn. Perhaps your thread was one of those. The lesson here, whether you choose to accept it or not, is to not jump into the forums without first getting a sense for what this place is like. You wouldn't expect someone trying to lead your group of high school friends before getting to know them... why would you expect that here?
As for the bands, well, that may be a matter that we just don't see eye-to-eye. Metal Archives has a very specific definition for what's metal and what's not metal. That definition is certainly not universal, and there's many people - even among the mods - that would personally disagree with aspects of it, but, it's a definition that has worked for us. We accept bands if they have at least one predominantly metal release. We define metal as music with a basis in metal riffs. There's a lot of people who think metal just means "harsh" music, or that metal is equivalent to what we here see as "classic rock," "mallcore" or "hardcore punk," but that's just a matter of opinion. With music there is no objectively, scientifically proven right answer. Music is subjective; each individual has their own sense for what qualifies for a certain style of music. It just so happens that, despite some differences, we have a lot of people who see the way this site qualifies what is and isn't metal as generally acceptable. It doesn't make us an authority on metal - unless people personally might think we are - but it does make us credible in our own right. In short, you might personally think a band is metal, but that assessment may not be shared with us. When you submit bands to our site, you must abide by our rules and our definition.
Beyond that, we do require evidence for band submissions. The burden rests on the submitter to prove that their band submission has at least one predominantly metal album released to the public. That usually means that they must provide samples of the music, so we can verify it. That also means that they have to prove that the album has been released and distributed publicly. That's usually just a matter of showing us how it's being distributed.
Thanks, that helped friend.
