Disclaimer: I may or may not make a similar post for Makai tomorrow. (Its f*cking 3:30 am here). Please do not turbo anyone.
Evidence
All relevant posts made by swamped, especially suspicious ones in bold, posts that are kind of exonerating in italic
DAY 1
198: Not really suspicious but very funny given the current claims
390: Gets afraid of the bandwagon she started against AB
453: Says Despair would not say they are Hope but deflect
(funnily enough, I don't think she ever said she is Hope until yesterday)
492: Unvotes in panic when she thinks her current target is the switcher (it's not)
652: "Maybe I SHOULD tone [my activity] down. [...] lol"
653: Has Hagi, Makai and francorp as top suspects. No confirmed Despair so far.
816: Posts a list with reads of Players she "hadn't had much interaction with". Not included is CzarTim, whom she had had no interaction at all at this point (Despite in the Despair chat maybe?). Also note that *Splinter has a solid Hope read)
DAY 2
1798: Her vote for crab because he immediately assumed kgtrep was Hope
1843: Announcement of read-list to come later on. Same pattern as with *Splinter's tables?
1864: Said read-list. *Splinter and CzarTim both Hope
DAY 3
2023: Speculations that Salve switched himself with the kill target. Note that the only possibility that could be the case is if he switched himself with AB, based on the movement info
2038: Again the anouncment for reads...
2060: Votes for Makai based on his fishy roleclaim
2111: Reaction post to CzarTim's reveal. I can't nail why exactly, but it feels a bit forced.
2116: Pressures CzarTim
2220: All the reasons why she "now" believes CzarTim's roleclaim.
2238: Casts doubt on crab (whom CzarTim will override later that day)
2277: Complains that noone votes (maybe she wants more to hide in)
2356: thought Makai's PR was to reveal a Hope-alignment. Phishing?
2358: paddles back from the maybe phishing
2364: Slight heat on Terrabyte
2410: For punishing CzarTim (doesn't mean anything that day as he wanted himself gone to use override)
2458: actually votes CzarTim as one of the first persons
DAY 4
2821: *Splinter not on her agenda for closer looks
2824: dismisses the Ninja theory
2829: Speculating on why no NK
2837: Further dismisses Ninja theory
2843: Thinks CzarTim attempted NK3 (he didn't)
2847: Introduces facility theory
2907: Disregards commuter/roleblocker theory as "convoluted"
3207: Glorifies *Splinter's documents as "very interesting to go through" (reminder: one of the two tables is copy-paste from Launchpad)
3213: Still going after AB, Swamped and Terrabyte
DAY 5
3296: Brings up roleblocker for deathless N4[
3220: Thinks of 3P based in CzarTim's role PM
3344: Brings up theory 2 Despair would be running around N1
3374: Against revealing *redacted*'s name
3405: *Splinter again not on the suspicious-list
3493: votes for AB
3722, 3750: Suspicious of *Splinter
DAY 6
3979: Premade post under assumption AB is still alive. That id the first premade post she ever made; could easily be fake.
4038: case against Sawneeks. (Note that point 3 could be used against her too)
4048: "Why did Despair choose AB?"
4104: *Splinter finally included in suspicious-list
DAY 7
4629: Says Despair would have bussed *Splinter. Had no votes on *Splinter.
Posts made by *Splinter mentioning Swamped
330: Doesn't like Swamped's first post vote, yet votes kgtrep
454: Defends Swamped
2288: Listpost with neutral verdict on both CzarTim and Swamped
3724: The elbow bump over Christina Mackenzie
Posts made by CzarTim mentioning Swamped
681, 734: Has both Crab and Swamped on the same Despair-Level
1698: listpost, Swamped "started strong"
Bonus round: Yesterday's voting
Swamped immediately went after Rest, despite mechanically it was unlikely he was the killer.
I repeadetly stated I would rather lynch Swamped than Rest.
The point is: Once one of us is dead there is no obvious target to deflect NK origins to. For Despair it is much more useful to have close neighbors (that doesn't count for NKs, tough because killing nearby people lowers the detection risk)
Verdict
From her behavior alone I'm not convinced. There are a few suspicious things (the most significant one #816) but also some very hopelike posts (e.g. #2837)
What strikes me as very suspicious are *Splinter's early interactions with her. His later interactions are more reasonable. That fits with the fact that he is a first time mafia player (if I remember correct).
