Ask HN: What can be done to protect/restore a Twitter account of a dead person?

Harris Wittels was a comedian and writer who passed away in 2015. He was the person who originally who coined and popularized the term "humblebrag" from his @humblebrag Twitter account (User ID 214680621). Both the account and term became a viral hit in the early 2010s and now "humblebrag" is simply part of our common vernacular.

It seems on or before June 6th someone hijacked his old account, deleted his old tweets, renamed the account to @micropicss and then to @differlanguages (there might have been other name changes in there too), and setup a spam bot. It also seems someone setup new accounts to sit on the @humblebrag and @micropicss names. The @differlanguages now has a few hundred thousand legitimate Twitter followers including lots of high profile users.

I have no relation to Wittels or his estate (which would seem to prevent me from opening an official complaint with Twitter according to their help bot), but I hate to see part of his legacy, Twitter's history, and the lexiconic record destroyed like this. Is there anything that can be done to get the old account restored in some way or at the very least stop a spam account from taking advantage of his account's followers?
