Filter the requests, and let the entrepreneurs know exactly what the VC is looking for and why they are looking for it.
I've found that VC's invariably have "hard limits" on the amount of the investment and the type of investment. In particular, I've never met a VC in the Hong Kong which invested in seed stage companies or is willing to invest in something under USD 10 million or is willing to invest in an idea. If you are looking for something like that, you aren't looking for a VC, you are looking for an angel.
So once you filter out who it's pointless to look for, then you start getting some leads that might be useful, and you can do a connection there.
