A user cannot unmerge a profile, that needs curator assistance., see https://www.geni.com/discussions/272643
For public profiles no permission is needed for merging. For profiles within your family group a user in the family group has to approve merges.
You should never delete profiles with other managers without first getting approval of all those managers. Otherwise it can be reported as vandalism and get your edit right restricted (there is no problem with deleting profiles where you are the only manager.)
If you are afraid a public profile will be modified with wrong information, you
can request to have it made a MP profile with fields and/or relations locked. See first post in https://www.geni.com/discussions/272715.
Yes I also find it annoying. I once had some one merge my great great grandmother with one of her nieces. I posted a notice of the error and someone un-merged the two, but then the same person revered them. Thankfully had this distant cousin involved, and he took care of it. But that has been my only issue.
I do of course make sure that I'm following all the profiles that I care about, and get a report when any of those profiles altered - A number of time I've went back and changed things back, but a lot of the time I leave things alone when the branch of the family is only tangential to my family line. And I always post sources when I've altered other peoples work.
But really if you don't want distant relatives altering your family tree you have to set your family up in a spreadsheet on your own computer.
No one has merged a tree of mine until you came along. You offer every hallmark of a con artist: I don't know you, you acted without permission or notice, and I have encountered others on this website -- long ago now -- who were simply collecting other people's ancestors for whatever their own opaque purposes were. That is why I am keen to 'keep it clean' for now.
I trust the information that I have recorded here, largely to preserve it until I retire and can look into the topic more deeply. (As well, the longer I wait, the more resources come online.)
The generations under discussion are troublesome for merges: many repeated names (Old Testament names were in vogue), many name changes after the journey to the New World, spotty records-keeping throughout the era, plus the usual nonsense of bad recall, bad translations, assimilation, blood feuds, old secrets, and, of course, dying young.
FInally, as to Geni, it is my understanding that this place is on its last legs, kept breathing only as a feeder stream to MyHeritage. I offer in evidence that when my uncle died, I was obliged to ask someone to mark him deceased because the editor controls had been locked down. I'm kinda astonished to see so much posting going on.
Dear Jeffrey I have to repeat what Ori already pointed out. Geni is all about MERGING, if you are not comfortable with MERGING you should not be on Geni. MyHeritage suits you better. By the way I trust Geni much more than MyHeritage due to Genis peer review. I have found errors very common on MyHeritage, much less common on Geni. Unfortunately mistakes occur in both and if they do Geni provides ample possibilities to resolve them TOGETHER, thats what Geni is about in my humble opinion.
Private User - I joined in Fall 2007, and yes, Geni has changed and changed and changed again.
And no, I do not like all the changes. But I do try desperately to keep up with the changing rules by skimming all Public Discussions for mentions. And in turn try to share the info.
Curators will jump in and help if you let them know of actual incorrect merges that have been made.
There are only limited situations when it is acceptable for a Curator to merge a Private Profile without permission from one of its managers.

However, if they could have merged or edited it if they were not a Curator, then they still can.
