How far back were you able to go in his tweets? I'm only seeing them back to 2014-08-08 when I use their infinite scroll and scroll back as far as it will let me go.
> A reasonable person reading that tweet stream could easily come to the conclusion that Rosario was a GamerGate person; he used the tag consistently and, in every case I saw, positively. I take no position (here) on the implications of supporting GamerGate, but do object to the paragraph you wrote suggesting Rosario should have been surprised to see himself associated with them.
In those, I see 23 occurrences of "gamergate" according to my browser's search function. The first chronologically are the two chastising the guy for the Nazi gas chamber remark, on 2014-11-13. Neither of them are using #gamergate as a tag to classify the tweet. The first was:
I just heard you say in the @Kingofpol interview that
everybody who are pro #GamerGate should be sent to Nazi
gas chambers
and the second was:
I don't take a public stance regarding #GamerGate, but as
chairman @IGDA_PuertoRico I have to denouce what you just
said
I don't see either of these as being either positive or negative use of #gamergate. They are there because that's what they are talking about.
The next two are on 2014-11-21, where he says he'll resign from IDGA Puerto Rico if they don't stop tagging him as an harasser. Note that this is only 8 days after the first two (and only two at the time) #gamergate tweets.
> In response to being added to the blocklist, he escalated, threatening to resign from IDGA unless they repudiated his inclusion on the blocklist. A reasonable person can argue that his response to the blocklist made this about his role at IDGA
The first two tweets, chastising the guy for the Nazi gas chamber comment, explicitly said that he was denouncing the remark as chairman of IDGA Puerto Rico.
I can see why he is upset here. He was chairman of an organization, and that organization was listing on their resources page a block list that labeled him an harasser. It doesn't sound to me like he wanted them to denounce the block list or his inclusion on it, but rather to just stop implicitly endorsing it by listing it on their site.
I see another 8 on the 21st and 22nd, 2 about the flawed algorithm of the blocker, one where he says he doesn't care about being blocked but rather about being labeled an harasser, one apparently in response to questioning of his relevance to game development, one apparently in response to accusations that he is censoring and sabotaging, one apparently in response to accusations of misogyny, one apologizing for the wording of the second tweet about the block algorithm, and one saying accusing people pre-emptively of a crime is wrong.
(Looking at the responses to some of those I see some mention of the GNAA[1] being involved. It was not clear if it was supposed to be GNAA members were trying to stir up things by making accusations against Rosario, or if they were saying Rosario is a GNAA member).
Over the next few days, there is one disagreeing with the use of the block list as a job candidate filter; one linking to a blog post he wrote discussing how to design a useful tool to deal with harasses and others by tracking complaints and documenting them, and starting a project to make that tool; 4 or so about Raspberry Pi using the block list; and .
There are no more tweets with "gamergate" in them until nearly 6 months later. There was a series of tweets on 2014-11-27 apparently in response to harassment targeting his family, where he said he thanked people for their support and said he was removing himself from further discussions on this topic.
The next tweet with "gamergate" in it is on 2015-05-25. It's about an Instructables project of his mysteriously disappearing, and he hopes it has nothing to do with some people thinking he is related to gamergate. (It turned out to be a glitch...apparently several other projects had disappeared and reappeared, and his came back).
It doesn't look to me like many, if any, of those uses of #gamergate are using it positively (or negatively). They are just using it contextually.
There are also a couple recent ones on the block list topic but not using the gamergate tag, such as a complaint about O'Reilly using the block list to prevent people from following them for OSCON information. In addition to the gg block list, BTW, they also were apparently using the atheism+ block list, and possible more. They were also blocking any friends of blocked people who tweeted asking why their friend was blocked.
