Lovely thought, but that would not include the other series, where after being posted for well over months long, deleted. "redundancy" of having an official chapter AND a fan translated chapter isn't redundant when one is behind a paywall that supports the author, while other is a typical MD chapter. Remove the MD, and now there's zero chapters on MD to read to public. Then again, if you also go along with 'redundancy' still, there's been numerous times where it's nearly required due to the poor quality or unreadability of a chapter. I'm not sure silas is gone to that extreme yet, but just due to an identical chapter being posted here does not exclude that the chapter isn't complete garbage. Then add onto another variable where different groups use different variations of the translations, where at worst case it becomes unrelatable to previous storyline (more notable with cultivation series that has large names where different groups shorten them differently)
TLDR: silas has a pattern that's gone beyond a singularity of occurrence, regardless of their 'reasoning' the action of chapter removal has been repeated enough to warrant advisement.
