I found many (100+) samples of – most likely ancestry/gedcom uploads – in the Swedish tree far beyond 1800. We have by now fixed several of them.
Sample 1: Anna Catharina Catarina Svinhufvud i Västergötland (Svinhufvud af Västergötland), + AD02 40G fdna
She was born 1736 – but this profile is fixed now (see revisions). It was uploaded by Johan Fält but it seems that he also now has started to change his uploads which got a strange numbering code. We are still working on fixing these uploads which is a tremendous lot of work. He uploaded doubles of many known nobilies in Sweden and changed their names and added suffixes with a numbering code. See revisions.

Anna Catharina Svinhufvud i Västergötland
Sample 2: Niklas Lovefall added several (I don’know how many) profiles with birth- and surnames like Iii:3 – these are not only suffixes, these are “real” names.

Erik Nilsson
Eric Nilsson was born 1728.
Sample 3: Molly Mills has added a lot of koded samples.

Margareta Warg
This is Margareta Warg with the code 5 and a conflict. Margareta Warg was born 1738 and many profiles have a suffix code.
We have started to clean up the profiles involved but we do not know how many uploads there have been and – even worse – will come. Instead of researching we spend our time to clean up.
“There are some restrictions, however -- you cannot import a GEDCOM for someone born before 1800, and all GEDCOM imports will stop once they go back to 1600. Read the full details here”
This is the claim of the gedcom-upload.
Does this really work? The profiles I mentioned are from the 18th century.
Furtheron I would think about the following changes (I guess you already have done this).
(1) Uploads will generate doubles and conflicts. A non-pro cannot merge and resolve conflicts.
(2) I frequently use MH uploads with original household documents and well done information of MH users. MH uploads allow you: main profile, husband, parents, siblings and children- that’s it and it works quite fine – before the upload every single field can be changed if necessary. A simple overwrite does not occur because it will result in a data conflict or a profile with the name “no name” and now I can fix the error.
(3) If a gedcom import shows a geni-match the uploader obviously can choose to use her/his information – which in sample 1 has resulted in that a lot of established names of Swedish nobility were changed and detoriated.
Only a curator can – I guess – open the list with the profiles these uploaders manage and find suspicious profiles. Everbody else is trying ro find these profiles in a jungle or in the activity list of the uploader.
The suspected uploaders I mentioned have added about 6000 profiles within 2/3 years.
Not all of them have a code or something else attached. Maybe 200+.
