I have an intimate knowledge of the rules of SOTA, having instigated and taken part in the last revision of the General Rules, but it takes threads like this one to show where the rules could still benefit from some revision.
I have just gone through the rules, and this has confirmed what I suspected from first reading through this thread. It may be considered strange, but in the GR there is actually no explicit prohibition of relaying signal reports. This can be taken to be an oversight, because I doubt that any member of the MT would be in favour of allowing the relaying of signal reports. It could be argued that relaying would be covered by 3.7.3 Code of Conduct, under “The Golden Rule is that all participants are required to operate in a manner that is in keeping with the spirit of the programme.” However, that spirit is almost undefinable, so although we Sotari may decry relaying we cannot say that it actually breaks any rule.
Antonio, EA4MY, also criticises the use of remote SDRs. This, again, is not forbidden in the General Rules. Chasers who use remote SDRs cannot be detected, so it would probably be pointless making a rule against it even if the MT were unified in condemning it - which they aren’t. The arguments for and against the use of remote SDRs have been gone over on this reflector occasionally, the question has not been resolved. I hope that at some future point the MT will agree some protocol to define how remote SDRs and remote chaser stations may be used, but at present the rules do not cover the topic.
