Ok, I seem not to be as suspicious as I thought I would be, so my paranoia might have been unbased, still, I'll tell you everything that has happened between me and breva, so that you can make up your mind.
Anyway,
there is no doubt whatsoever that pofa is BO.
Kogoro's analysis cannot be slandered or anything and I guess no-one should distrust breva at this point.

ALL townies have to vote for her tomorrow, since the numbers are pretty close and the BO might be able to poison one or two people.
We cannot allow them to outvote us because we have to prime suspects for being BO (as has happened in round 15).
As you might remember, I had arrived a bit late, so breva was the only I managed to contact before night 1 ended who actually could be investigated. She offered me her interrogation for investigation. I was a bit surprised that she told me that, to be honest (but it makes sense if she's Kogoro) and warned her not to let anyone else know and I didn't tell anyone else either, of course.
My guess is that pofa is Gin and slandered herself, but it's fair to assume for youse that I am BO or even Gin I suppose.

After night 2 had ended, breva told me that pofa is definitely BO and that I have to trust her on this. I was a bit confused, but I thought to make up such an inbelievable story wouldn't make sense for a BO.
Then I read the thread and saw that she had posted that "she found pofa out on day 1", which caused me a great deal of panic, since I instantly knew that she was Kogoro and was afraid that the BO would probably be able to figure it out as well.
I contacted her about that, saying that I think that was a mistake and that she should be very careful if she didn't want to get APTXed. She told me she wasn't Kogoro but had re-interrogated pofa after coming to suspect that she was
Korn and got a different result this time.
While this eased my mind about her getting potentially APTXed, this also meant that there was just a 50/50 chance pofa was actually BO and it also meant that breva seemed to believe I was BO and had pofa slandered. As you might have noticed, I then tried to convince people to vote for pofa, but to little avail. As you probably all know, the DBs had her identified, discouraging people to vote for her. This takes me to my next point:
The "DBs". Who have they actually identified? They tried for xpon on day 1, and, surprisingly enough, he was lynched.

On day 2, they "identify" pofa. Has anyone heard about their results? Because I haven't. And there is another thing VERY suspicous about the person that's claiming a DB:
I got breva in contact with them (they might have been in contact before, though, since breva didn't trust me, obviously) so she could get identified and we could actually get pofa lynched. I told them the whole story why I think that breva is right about pofa being BO, mentioning that I had initially thought her to be Kogoro. They told me that was indeed the role she was claiming. So, why would they tell me her role? I'm not exactly trustworthy atm!
In conclusion, I AM willing to do as much as I can to prove I'm actually town by day 4, but I WON'T give the DBs my role for identification. And I advise everyone to be wary of them as well.
I also have a few well-founded suspicions about other people. They are going in my will NOW, so I'm basically challenging the BO to erase me. In fact, I think I even know about a crime someone can be arrested for, and I'm almost positive I'll know for sure by tomorrow. (Megure could do it tonight, I suppose)
So if you are police, or know a police, please get in contact with me.
