Unfortunately, removing that limit would make server load worse as we’d be overloading the db for every infil and/or request to news. We’d trade better performance for any time players aid-spam for worse performance any time players read their own news.
The larger issue here to me is that sending aid takes so long. 
We should be able to support more than a handful of simultaneous aid requests.
As a short term fix, we can limit how frequently a single player can send aid. I’ve added Rate-limit aiding to #roadmap:to-do.
