why are all of this old yaoi mangas suddenly getting updates?

at least this one is valid. All the other's I've seen this month, were all duplicates already posted in their proper places.

Sometimes I think the uploaders are just messing around to cause trouble for mangago

that’s weird? haha

i guess because of quarantine ╮(￣▽￣)╭

Not really, uploaders have been uploading items previously posted, for years.
