This proposal is admittedly the result of frustration, but the problem has been going on for several months now, ever since the new merging process went live.
When a merge is proposed between a Public (green privacy) profile and an Open (white privacy) profile, and there is no response from the managers of one of the profiles (it does not matter which), the merge becomes default-approved and, in the list of Pending merges, it is listed with the message "You can complete this merge after a final comparison". This message is incorrect, because only a member of the trusted list of the Green Privacy profile can complete the merge. Nobody else can. The situation is the same when both profiles have a green privacy level - the proposed merge looks like it is default approved, but it can't be completed by anyone (except probably someone on both trusted lists).
Example here, from MatchBot's proposed merges backlog: https://www.wikitree.com/index.php?title=Special:BrowseMatches&type=pending&order=datedn&canAct=0&requested=1
I'm asking that Green privacy profiles be treated like Yellow, Red and Unlisted profiles in proposed merges - NO default approval, NO message hinting that an arborist might be able to complete the merge.
I'm aware that this proposal goes against the "one tree one person one profile" objective. I contend that it would still be better than inviting users to complete an action they have no rights to complete.
