I think the Wikipedia article on Entryism might be somewhat relevant. This can be defended against by having a weaker signal as you propose.
On the other hand, there is also the issue of people who popularise and simplify concepts. I suspect that this is the reason why so many people were unhappy about Intentional Insights. I suppose the debate comes down to whether it is better for people have partial understanding of an idea or whether this is counter-productive because then people are starting from a misconception, rather than nothing.
