[WikiEN-l] Sockpuppets?

[Meg Ireland]

Something just struck me as very odd with some edit patterns:

User:WesleyDodds
User:75pickup

Are they one in the same person? I noticed they both just edited the
Led Zeppelin II article, and looking back at their contributions I was
surprised in noticing they edited Oasis and Primal Scream at almost
the same time periods, for some months now.

Then User:Indopug appears on the December 24th, I noticed very similar
editing patterns as well.

Led Zeppelin II, Stone Roses, The Smashing Pumpkins,
Wikipedia:Featured article candidates/Joy Division, clasifying every
article B class... etc

What gives?
