Reporting Multiple Times

[StellaInTheSky]

During my pre-work privateering today I boarded a public ship that had a disgusting player on it. He started out making inappropriate comments in the local chat, then went to whispering to me. I reported him. We sank shortly after and I'm having major glitch problems with SVS lately, so of course I glitched and had to log off and back on. I went back to the ship I was on and he began making even worse comments to me. I let them build a while then tried to report him again, and it said he'd already been reported and wouldn't let me do a second report.
My question is, why? I was enjoying the crew and SVS battles on that ship, and I didn't want to switch ships just because of one person. If his comments got progressively worse the second time around, shouldn't that be something I can report again? I didn't say anything back to him other than telling him (in local chat, because another crew member had heard some of the earlier comments) that he'd been reported once and needed to stop whispering gross things to me. He eventually shut up and left the ship but it really irritated me that it wouldn't let me report him again. Is there any particular reason they won't let you report multiple times, or just another feature of PotCO that maybe needs tweaking?
