Can it be considered spam when a user is posting in the same thread for over a month now and immediately deleting their posts right after? I keep getting notifications of a user "kdrama22" (Display name "Lemonade") who's ghost-posting in the "MDL's 2021 Watch Challenge Discussion Thread". There's not one actual post in the thread by this user. I contacted them via DM and kindly asked them to stop, to no avail. The last "post" is just a bit over 30 minutes ago.
