Comment:

 I feel like we need to provide incentives for people to actually give
 bridges to friends. From an egoistic point of view: why would they do
 that? Distributing bridges to other people increases the probability of
 the bridge getting blocked and the system classifying you as a "bad user"
 (I'm a pessimist).

 Another problem might be the first node in the invitation graph: the users
 who receive bridges first. If we only have a small set of trusted people,
 the entire system might be ineffective. If we have some automated way to
 handle this, then we can expect large-scale sybil attacks like the
 bridges.tpo crawling.

 Some papers which thought about models for this problem:
