On neutral assistance:
Neutral logi is only a concordable offense under a specific set of circumstances (taken from the dev blog I previously linked)-
- is involved in a war (including normal wars or FW)
- does not share a corp/alliance (or FW side if the war in question is the FW war) with the assistor
- is engaged in PVP (has a capsuleer logoff timer)
- Is in highsec
I have flown logi in highsec since the changes in the dev blog. If someone had a kill right activated on them, we either all set safeties to yellow and continued repping/cap chaining with him, or left him to his own devices. If we all had our safeties set to yellow, this caused the suspect flag to spread to other pilots, but no one got concorded. So, unless the rules were changed again (I cannot find a dev blog stating so), this is how it still works.
Once again, make sure that no one has red safeties to avoid surprise concord parties.
On throwing valid war targets into the mix:
Hell if I know. I know that people have gone flashy while in fleet fights against war targets, but I can’t say for certain whether or not they were being simultaneously being attacked by a neut who activated a kill right and an activate war target. That being said, I find it doubtful that suspect/criminal flages would fail to transfer to those offering remote assistance under any circumstances. If there is a set of circumstances under which that can happen, it is probably unintended by the devs and/or considered an exploit.
On yellow flashies
If someone has a suspect timer, your can rep them, but only if you also set your safety to yellow. This will cause the suspect flag to spread to you. If your safety is set to green, it will prevent you from rendering remote assistance.
Also, just in case it wasn’t clear, yellow flashy and suspect flag are the same thing.
