If they are not a friend or a guildie - to be honest, do not worry about it. Those players that are in your neighborhood are only around for a couple weeks and then reshuffled (vast majority) in the bi-weekly reset. Really, depends on your play style. You can play like a predator or prey - or somewhere in between. If you strike strong relationships with those on your Friend list and your guildies, then basically the neighborhood (aka 'hoodies') are there for you to find deals.
There are snipers galore everywhere. If you are contributing to players in your neighborhood, make certain you are making 'secured' contributions - meaning that nobody else is about to knock you down in positioning - a secured contribution means a guaranteed return on investment. Anything less, then there is every expectation that someone else (aka snipers) will find a deal thereby knocking your position down and guaranteeing themself a return.
If you are just looking for some blueprints or medals, dropping a FP or two on a fifth place position is likely to give you that reward - unless there are FPs also available for Position 5 (in which case, again, snipers will be looking to make a deal).
