Frankly, it boils down like this.
1: If you remove tags for things you _do not see_ in an image, you get a warning.
2: If you add tags for things you _do see_ in an image, you get a warning.
3: The admins make assumptions as to whether or not you ignored warning 1, when making change 2, and block you from the site for that incorrect assumption. (I did not ignore the warning for a completely different action, that doesn't apply to this one.)
4: Two different people can look at the same image and see different things.. and neither are wrong.
5: The things I got warned for are poorly-defined and in some cases neither set of tags (pre or post my edit) are completely accurate. In that case I'd rather err on the side of having no tags at all.
6: The messages you receive when being warned, have no method for contacting the one warning, to ask for clarification/dispute them.
Anyways, that's all. Since tagging = getting warned, I will no longer tag.
