Got these messages saying that them and their mutuals accidentally reported me instead of a scammer with the same profile. This account had only been active for 3 days, reposted a few posts that first day and nothing else, hasn't liked any posts, only follows Tumblr, and between when they sent their first message and last a few days had passed and while it showed them as active, nothing changed in their account. No new reposts, follows, likes, nothing. Seemed fishy. So, I did some research and it seems the Discord account alert scam has made its way to Tumblr. Heads up for anyone who uses it to look out for.
