I've come across this and I thought that for a lot of you it could be interesting.
Site: Minecraft, in general.
Entries: 11 Different Databases. I could not tell the exact number.
Dump date: Between 2015 and 2018 (most are recent).
Additional Details: Unchecked databases. Some can be hashed.
(I do not know if the format is correct. If there is a problem with the format, I give free permission to the moderators to edit it or let me know)
Would you like guys a second part with more Minecraft databases? Comment it
Thanks, 3X1L3D
