Zawawa-sensei deleted all artworks after a bunch of Chinese people flooded this tweet with a nonsense meme.
A mainland Chinese meme emerged recently,(Personally speaking, a really bad one) which involved an SNS screenshot in which someone had this artwork as an avatar. After people found out the origin of the artwork, many - pardon me - idiots flushed into the original tweets and flooded the Zawawa with the meme. As a consequence, Zawawa-sensei deleted all artworks on Pixiv, privatised the Twitter account, after stating such misuse of the artwork and nonsense flooding are really upsetting.
Personally, I feels really sad and shaming on this issue, realising the trouble and unpleasant experiences Zawawa sensei had, and such trouble are caused by ones from the same country as I am. Sorry about this incident.
Attempting to run this through google translate did not post hopeful results.
MandekaluCavalry's post is basically furious words from an Eli-Nozomi fan regarding the recent issues surrounding this artwork. And actually, the first paragraph would be Google-translated correctly.
