The bulk update request #9319 has been rejected.
create implication stealth_* -> stealth
Most of the tags (below) with the prefix "stealth_" should imply the 'stealth' tag. Or, if that is not applicable, possibly the 'public_indecency' tag.
Take a look and see. Stealth has very few posts in it right now.
Also see public_indecency as I mentioned
