Obviously:

By the way, I missed the twitter feed the first time : https://twitter.com/necunoscom
And found this pdf document on their website : https://necunos.com/rcm.pdf with this name on it :
We know someone in this community with this name, mostly by is nickname locusf.
There is an old tweet containing the name of necunoscom that he retweeted so could really be from him.

That would also explain why the people who retweeted the 2 tweets from the account of necuno are from the Nemo community.

At least we have now an idea of who is being it, so may not be as big a trap as other were. We'll see what they propose in the future, but it looks like with a CPU that old that they only target people like on this forum, which so far lead to projects in small quantity with small team, so high price regarding performances and big delays. But would be glad to be wrong !
