What's up with these inconsistent bans?

[Falcon]

Hey guys! Tony here. I was just scrounging around the ban and blacklist pages and I have noticed some interesting trends. Why are players who do one thing getting banned for a month while players who do the same get banned for a day? These inconsistent bans are becoming more and more noticeable and I'm suggesting that there should be some regulation when it comes to ban times. Obviously there are many variables that come into play when banning a player, though I think a spreadsheet or something of the sort to minimize inconsistencies would be beneficial to the community.

Thoughts?

Thanks,
  Tony
