well, its bee a long time since i've seen a boycott, last i remember, you pick a country, and every one votes for/against, when their is like 10 more, for, votes, then the boycott kicks in, the more votes for, the more products the boycotted country is unable to buy. votes roll off after a certain time, and can not be revoted for a cooling down period.
direct contracts set up prior to a boycott, bypass the penalties, but new contracts can not be created, until the boycott pass. in the past, every one, pretty much, would set their trade strategies to hold 65 months worth of everything, as boycotts last 60 GM, so if you had everything stocked, they only thing that would really hurt is that your corps would suffer.
boycotts, early on were devastating, until players figured out how to minimize the effects. then the whole process became less popular. as the players that generally earned boycotts, where well prepared to handle them.
but then its been a long time
similar to boycotts, are the SC ban on nukes. it only bans the particular country, not player, for using them, or buying them, depending on the resolution. and direct sales still bypasses it. they really where used more for the sim-community to vote to say some one was going over board, rather than doing actual damage, same with boycotts
although, i tell you, i really don't think this deserves a boycott. things like this happen all the time, no telling who did it. and even so, if your really concerned about things like this happening, form a CM, for the express purpose of preventing this. kinda like econ league/fed or something.
when i was new at this game, the 3 biggest money maker corps in the game where Oil, EP, and FMUs, their was a player that dumped so much on at one time, on WG, that it literally took 3+ months for the market to recover. this kind of thing happens allot. if a market is usually heavy red, and goes bright green, let the price fall, then start buying, the price will come back, and you can piece meal out your stock pile, making a profit. things to watch out for, if if corps production is increased, or if one of the major corp consumers of a product have reduction in consumption.
it really pays, to spend time getting to know the flow of material. my favorite "supply train," is the AT, HTS, Service. AT only supplies 4 corps, but the 2 biggest users are HTS, and Service, it is one of their largest raw material. and service/hts are used in everything else. so if corps are closing, the demand for HTS will drop, HTS will go green, and some of those corps will close, creating a ripple effect on AT, making that green, dropping the price, and when HTS goes red again, corps open, for a short time the AT prices will be low, manually buying AT, at the appropriate Q for your HTS corps, then manually stocking them, might help them through the resulting AT shortage others will experience
shrug, sorry for rambling
