PSA: The person who goes by the name Nicole Travis has been spreading hate and negativity not only in the Fairy Tail community but in other fandoms as well.
This post, however, will focus on the Fairly Tail community
She has created at least EIGHT anti-Gruvia blogs on Tumblr alone (gruviaistrash, thegraylushipper, anti-gruvia-blog, grayluforever, graylunation, grayluftw, gruviahater, and xterier) and has shared similar hate content on other platforms, including DeviantArt, Twitter, Facebook, and YouTube for several years. Her posts appear across many Juvia-related spaces, so I have come across multiple accounts of hers sharing hate content.
She expresses a strong dislike for the Gruvia and Nalu pairings; however, her posts often contain misinformation, spam the feed with repeated hate content almost every day, and include insults directed at members of the fandom as well as the author. She has also been messaging different users not just on Tumblr to encourage hatred and has formed a group solely for sharing such content, though it's unclear whether the group still exists today. This activity is disruptive to the community.
I suggest blocking her accounts, though it's possible she may create new ones. Everyone can ship whichever pairing they like, but please make sure to share accurate information, not misleading content, and express your opinions in a healthy manner. Let this post serve to raise awareness of these ongoing issues in the community.
