Very much this. Tumblr has features which seem designed to actively encourage harassment. The quote-tweet feature which that post about Mastodon the other day complained about? As this points out, Tumblr's had its own version of that since the very start, and unlike on Twitter deleting your post does nothing about the quoted copy. It also allows anonymous asks by default, which are widely abused to harass and threaten. It also has an utterly toxic culture built around all this which the press seem to downplay for political reasons, just like they downplayed the Russian influence op which reached pretty much all of Tumblr whilst writing endless articles about Facebook and Twitter.
