someone or a community spam yahoogroups
I haven't check email from yahoogroups for long time. But today two emails attract my attention.
It is from yahoogroup [backpackerdunia] and [bukukita].
[Backpackerdunia] is yahoogroup about traveling, and [bukukita] is about books. All in Indonesian language.
But both yahoogroups send email about criptocurrency, in english.
since March-April 2020.
Please kindly recheck your yahoogroups. I don't think this is bugs but someone or a community spam yahoogroups.
