I like this idea a lot : many is the day spent fruitlessly cruising the plunder pages looking for meaningful targets to be hitting : having a choice of the gossip page entries would really add some spice to matters : and I think 3 hits per day is reasonable. At first glance, Grants objection seems reasonable too, but then it would be a terrific waste of those 3 points when a handful of FOj's/HN's would light up that sort of target with 50 fleets to be hit : I like the 24hr cool-down on repeat hits as well, which would go some way to mitigating any 'bullying'.
I do think fame gain/loss has to be over-hauled : currently it takes no account of relative strength/value of fleets involved : I think some calculation, maybe involving fleet total hit points, should act on the fame % gained/lost : a lesser fleet defeating a nominally more powerful one deserves more fame than vice-versa : A sotl fleet beating up unarmed traders deserves little to none, IMO, it major 'meh, so what'-type event whereas an LMM fleet beating off a frig-led raider is a noteworthy 'wtf!'-type achievement and should be recognised as such in fame gained.
