In his defense, the wiki does start out by saying "Bondage is the physical restraint of a character achieved via the use of objects or tools (such as shackles and chains, rope, straight jackets, or stocks).". And despite the lengthy write-up, no mention was made of allowing tentacles. So it wouldn't necessarily require mentioning just to add a line like that to the wiki.

I've edited the wiki, re-adding the line he removed and changing the line he added to:
  • Do not tag when the subject is only bound/restrained by tentacles, monsters or people without the use of tools.
