I remember clearing some land a while ago, and finding a hole that dug straight into the ground. I almost fell into the hole and died, but the shift key saved me. Anyways I think it lead straight into a spawner room because I remember mining moss stone after using an enderpearl to get down. Should I have reported this before? I didn't think of it to be of any importance, but looking back on it, just wanted to make sure I wasnt doing anything wrong.

Reporting it would help us keeping xrayers away from minetown. You are not supposed to report it, but it would help minetown <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>

should I do it privately or on the forums?

Making a PE would be fine.

i checked the hole antonyoo found, it was too old for the HE logs to catch. looked around and found another one, same case.

Also, if you find an x-rayed dungeon, please dont mine the cobble under were the spawner was, it makes it harder the HE.

lol, its like a minefield

Yes if you see anything that seems like it was done using XRAY please make a petition at the location and report. You gain a lot of respect for doing this and you stay anonymous x
