Sync

My mistake; you pass the request into the SteamCommunity constructor, then pass that SteamCommunity instance to the TradeOfferManager constructor as the community property.

Yes, you won't really be able to run more than 10-15 bots on a single IP. You'll need to use proxies or multiple IPs on your machines. You can have steam-tradeoffer-manager use a proxy by setting a request instance with a proxy set using request.defaults to the TradeOfferManager constructor.
