It's a cycle that's in fact very noticeable in Bitcoin and crypto. If a service starts becoming more popular in BitcoinTalk, the scam accusations start to come one after another made by "brand new accounts and newbies". It's becoming very obvious that there's some probability that either it's the same person behind those accounts, or it's a group people who know each other and who are working together.
Sometimes people can complain about services, platforms that don't have announcement threads in Bitcoin forum, but mostly they complain about platforms with announcement threads and representatives here.
Anyway they need to know that Bitcoin forum is not their main places for complaints. They must complain it mainly on that platform, like in chat box with customer support staffs, or with support tickets in email, or social media of that platform.
Most of complaints from newbies are invalid.
It's an illustration of a Sybil Attack. Add them to your ignore list.
It's invalid accusation attack, not Sybil attack. I know you want to use "Sybil attack" in purpose but it can be misleading, let "invalid accusation attack" as it is.
