This should be an Error, not info.

In which case do you expect seeing more than one sender?

Currently, the only call to this method passes one sender

…ght need to pass it to protocols and back to gossip in validation phase). - do not propagate old messages. (ever) - remove global invalid cache, since we'll never propagate twice even if valids - maybe remove gossip "invalid" reporting since we'll only propagate valid and won't save old. (we can keep it for future use.)
