@Semmy1960 I have moved the posts related to your particular case to this topic, so that the conversation at How to resolve the problem of IP and user blocks in African editathons can continue focused on addressing the general problems.
Question: can you edit your user talk page on Wikidata? If you can, I suggest you follow the steps described at Wikidata:Guide to appealing blocks - Wikidata.
As I have mentioned in another post, if you could provide a public link of that editathon or any other Wikimedia activities you have been involved with, that would be very useful for your case. Wikidata admins only want to block Wikidata vandals, and you clearly are not one. Show them some prof publicly and I believe your case should be solved soon.
