There's no reason to lie, people can read the comment I'm referencing but I'll quote it here:

>> What about modelling geopolitical scenarios?

Which is nothing like your description of it. And then your collaborator, or someone using their name, also commented with:

>> Good! Really interesting idea!

Those comments are written as if they are not involved in the project. It's dishonest, not "aggressive".
