Because Nacho seems to think it's important, I'll check out tvella's ISO (summaries in normal font and my thoughts in italics):
ISO 0-1: Votes DH then claims not to have read the other pages, but keeps his vote on DH. Asks what next play is.
Okay so far, but his question at the end leaves it hanging that he might unvote given the proper reasoning on the next play by DH.
ISO 2: Unvotes DH for saying his plan is to lynch boberz for his response to the "trap". Says he is unsure that boberz's actions are lynchworthy and the previously discussed, "Let's see where this goes."
Obviously the last sentence is scummy for the wait-and-see attitude. Usually there is some speculation as to whether this is actually going on or if the person is just unsure on their read, but here he says that's what he's doing himself. I don't really understand how boberz's actions aren't lynchworthy (or even voteworthy) but DH's suggestion was. If you are willing to accept that DH's suggestion was a trap to catch someone like boberz, then your vote logically should go from DH to boberz. This implies to me that tvella doesn't want to be stuck on the DH wagon anymore, now that he no longer seems like a fool, but also doesn't want to jump onto boberz for something others might not find scummy. This whole last part is just major speculation by me though.
ISO 3-4: Promises content in response to Hiraki (who gave him a "needs to die"). Says he wasn't following by unvoting DH but would be following by boberz. Gives Sens a town read for his scumhunting and Darla a scummish read for gut reads on a possible deflection to sotty and being overly defensive. Votes Darla.
Obviously I can't argue with his conclusion, but now that I see this again, I find it a bit odd that those are the tells he chooses to go with for the vote (as opposed to the earlier things that I mentioned or I assume boberz mentioned in his vote). I don't really buy that he decided DH had town reasoning but incorrect reasoning (i.e. the whole trap was useless, but not scummy).
ISO 5: Questions Darla's 'contradicting play' reasoning for her vote when she could be accused of the same.
This was in response to Darla's fabulous post where she admitted to completely screwing up for the beginning of the game and tried to find some reason to vote someone (in the end not providing much reasoning). I see nothing wrong with this post.
ISO 6-7: Defends his vote from SA's suspicions and says SA thought the same thing earlier but didn't vote. Laughs at Nacho's vote on him.
His defense of his vote isn't bad. I can't blame him for laughing at Nacho's vote either since Nacho didn't seem to give any reasons the first time around.
ISO 8-10: Further defense of his Darla vote against Llama, DH, and Hiraki.
Somewhat redeeming here, I think. Obviously as scum he couldn't just abandon ship here without looking scummy, but these posts make me believe he actually does find Darla scummy (or at least he thinks there is enough of a case there for him to keep pushing). Either way, not so scummy.
ISO 11-12: Declaring V/LA for 24 hours (promising more activity after that), which he overstepped about 25 hours ago.

Conclusion: I came into this ISO thinking I was going to be voting him at the end (especially for ISO 2), but his last few posts (before 11-12) kind of changed my mind. I'm leaning town on him now.
