@filippo I definitely agree that robots.txt is not the way to convey the limitations of a source forge.

But proper sync between the various nodes of the proxy instead of redundant deep clones for each of them (which from my armchair look to be the reason for such a high number of requests on the same module) would be a low hanging fruit ready for picking in my opinion.

And I think the xkcd falls short if you consider the amount of time/resources fixing the issue would save everyone else.
