I’m afraid I don’t have any knowledge of how their scanning works. If they think it’s an issue with GenerateBlocks, it would be helpful if they could contact us with more information on why they think that – I’d be happy to resolve it if it’s something on our end.
However, if it’s an issue with GenerateBlocks, it will likely become an issue with other block plugins as more dynamic blocks are released/used by their users, as GenerateBlocks is using 100% core WordPress functionality.
Thanks! Sorry I can’t be more helpful for the time being.
