i think don't lock announcemen thread
you can explain if member or investor ask about project, you can self moderate if newbie account or another people comment out of the topic you can delete, if you lock announcement thread i think investor down trust youre project, and investor can believe if youre project is bad
i think it will be better to not lock the thread and rather EXPLAIN HIS SIDE. those trolls has already presented proofs of there arguments. so i think the team might be better to explain or present their argument to. if he will make a new self moderated thread then he will be able to control the thread but that it will only means that they are running away with those accusations and so that other investors wont see that, if the are serious then they should be transparent and face those trolls rather than run away from it.
There is no clarification rom dev about issues scam. They chose to lock ann thread than give us explain about issues. Maybe what many people said if this project scam is true.
i think the confirmation on above is enough
