  • Comparing the dewiki behavior of PF75172 and MalDabei, with the "Likely" above and the more detailed technical insights from the dewiki CU result in mind, seems to justify the existing block and a sockpuppet tag. Specifically, the initial mass editing of inline citations ("Einzelnachweis(e) besser formatiert" edit summaries of PF75172, ^{[1] [2] [3] [4] [5]} "Bot Meldung erledigt" edit summaries of MalDabei ^{[6] [7] [8] [9] [10]}) in a wiki that automatically assigns pending change reviewer permissions to users according to open, edit-count based criteria ( de:WP:Sichter) is interesting. MalDabei has automatically received ^[11] the permission, and actively used it to review contributions from verified company accounts such as [12] and [13]. ^{[14] [15]} PF75172 was blocked before they could obtain the permission. ^[16] We can only guess what it would have been used for if the approach had been successful. ~ ToBeFree ( talk) 21:08, 7 September 2021 (UTC) reply
