Of course. But there are also very real cases of people quote-posting someone with an opinion they don't agree with, leveraging their follower-base to start dogpiling. Even without the harassment problems, this is already not a very good way to have a conversation, as you'll end up with a ton of people with the same viewpoint replying. But then things can go even further with people starting to send death-threats and other niceties of this kind to the OP - which is definitely harassment territory.

Currently, there just isn't many good tools to protect yourself against this kind of dogpiling.

Personally, I think both are necessary: A tool to protect against using quote-posts for dogpiling, and another to correct misinformation.
