EIA has a large amount of overlap[1]; similarly large overlap with confirmed DC sock.
- Note especially the histories of articles like [2] (all 5 non-procedural/bot edits from last year are from DC + sock and Landpin) or [3][4][5][6] where DC and Landpin are some of the only editors
- Both accounts edit near-exclusively about UK law and politics, but they also both edit about stuff like Canadian law [7][8][9], sign languages([10] vs [11]), or German politics/law ( Schleswig-Holstein laws [12] vs [13][14][15], more generally in [16] vs [17])
- See especially edit overlap in category & template namespaces, [18][19] especially in more low-edit pages like [20] or [21]
- Note Landpin manually undoing GirthSummit's rollback of one of the DC sock edits ([22] vs [23])
- Lots of requested-move related activity (DC [24], Landpin:[25]). Landpin's sixth edit was actually starting an RM [26] and they very early on displayed an understanding of the nuances of the disambiguation policy [27]
Landpin has created[28][29][30][31][32][33] or worked on [34][35][36][37] lots of articles from DotCoder's old to-do list[38]
Both translate articles from German (Landpin: [39][40][41][42], DotCoder:[43])
Both accounts' top edited namespaces are Article, Template, Category, and Talk, and note the similar time zone (Landpin is a bit more consistent, but the DotCoder account existed for over 10 years)
Both use very short edit summaries; see the archives where Chlod looked at how often DotCoder + sock used summaries like "fix" or "start", and compare with [44] and [45]
Both accounts have a similar way of breaking up their sentences when speaking casually. (Compare [46][47][48] and [49][50][51])

They have similar timecards (differences should be explained by the fact that the DC account operated for 10 years, Landpin less than one). Landpin edits more. Landpin doesn't appear to have edited modules, but that was called out specifically in the last SPI investigation as what drew Chlod's attention to them. I've been up for the better part of 24 hours, so please pardon me if I've missed anything stupid like them taking opposite sites on when sentence case should be used in article titles or summat.
