This user has recently posted a number of questions here on Skeptics about controversial recent political events, sometimes concurrently cross-posting on Politics.SE, sometimes self-answering. Most of the questions have been downvoted and several closed. In a comment on this since deleted post, the user states:
I've been trying to use StackExchange to publish my attempts to do fair-minded, possibly neutral, Internet stuff on these current events
This seems to fit with the previously discussed behavior of using comments to discuss off topic political elements edited out of their otherwise on-topic questions.
We don't care about your political opinions, cross posting is clearly frowned on, and, while self-answering is part of the SE model, it seems the community wants to avoid users turning this site into their personal blogging platform.
Is there something else we should be doing in response to the posting behavior by this user, or should we just keep applying the quality standards and bringing readers attention to cross posting in the comments?
I can't see other deleted questions, but it seems, with some of this user's questions being well received, s/he may have an overall positive question record. There may be a "throw everything at the wall to see what sticks" strategy involved here, or a lack of understanding about the purpose of this site, but from my perspective the user may have some positive things to contribute, but the overall effect has been negative.
