All the griefing you listed are painfully obvious forms of trolling, rescue isn't which is the problem with it, and that's part of why people have been asking for it's removal or an option to opt out of it since it's inception, alongside people not liking having control of their character taken from them at another players discretion.

If your anecdotes are valid, then so are mine because every time I've personally been rescued in DF it's been at best pointless and annoying, and at worst the cause of my death.
