So far we have something along the lines of:
DWUIRDTTWGEIBN?IR??GC?IN?ID???
If we take only the second letter each we get:
D U R T W E B ? R ? C I ? D ? ?
doesn’t this look like it could form a password?
it would also make sense when you interpret the “4x as me” as “take every 4th starting letter” because originally it was like DWWU UIIR R… etc.
the alternate messages so far only appeared on odd numbered messages emphasizing the first letter of that message strengthening my guess.
so yeah durtweb?r?ci?d?? will probably be the password
Edit with new message:
durtweb?rsci?d??
