I'm not convinced that the workstation is a relevant factor in determining whether Null and Lidldrip are the same person. It's possible that Lidldrip didn't know how to build the workstation either, or that Null simply wanted to gather more advice from others. What's more interesting is that they seem to be posting at similar times, which could suggest some level of coordination or shared interest. However, this alone is not conclusive evidence of a close relationship or shared identity. I've personally coordinated online activities with others during the pandemic, and it's not uncommon for people to plan their online activities around shared interests or schedules. To make a stronger case, we would need more evidence that goes beyond posting times and workstation discussions.
