Possible vandalism on Feb 13
I'm seeing possible vandalism from yesterday by two new users:
Sarute - multiple nonsensical tag type changes
GeeXuan98 - changed rating of nude image 603413 from q to s

I've reverted the changes by Sarute except for tag 'hito_komoru'. I don't know enough to tell if that change is correct or not.

Post 603413 changed back to original 'q' rating.
Thanks for your report and your reversals to wrong edits!

These users were possibly doing edit tests, but I'm sure Mods will do something to them if they continue doing these wrong edits in the future.

And yes, "hito_komoru" is an artist tag, and so it's correct to keep it like that.
Of course, they will get banned or possibly account wipe.
