Rule Clarification: Tagging without intent to fight

[Edmund Barbarossa]

I recently posted a tribunal in which a player tagged my fleet but made no attempt to actually engage me, and did not fire a single shot during the battle. Admins said that this was covered under the new rules and changes to in-battle tagging with the % damage system, so I'm looking for some clarification here. 

Are we allowed to tag enemy players with no intent to actually fight or chase them in battle? Are we allowed to do this indefinitely to lock them in for 8 minutes several times until we get backup? I thought that this would constitute griefing, but if this is allowed with the new % based tagging mechanics then that will significantly change the way I play.
