We introduced banning of peers who spam us with the same request (more than 2 times). However, we missed that it is completely legal to send the same request multiple times as long as we did not provide any answer. An example for that is the justification request. This request is send multiple times until we could fetch the justification from one of our peers. So, the solution to this problem is to tag requests as fulfilled and to start counting these fulfilled requests. If the number is higher than what we allow, the peer should be banned.

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
