*Regional Advertising Spam: Regions can advertise themselves either via Telegrams, or in the Gameplay forum as per the requirements in the Guide to the Gameplay forum.
The rules on sending recruitment telegrams can be found in the FAQs. Most importantly, they must have the "recruitment" checkbox ticked before sending. Note that there are niche circumstances where a telegram encouraging a nation to move region may not require the recruitment checkbox be ticked, such as a region schism resulting in the community splitting between two regions, a telegram asking a member of your region's military to deploy to another region on a mission, a region relocating its community to another region, or a welcome telegram that encourages nations to move to another region. We strongly encourage you to seek a ruling on your situation first via GHR if you are unsure whether one of those exceptions applies to a telegram you intend to send.
Posting regional advertisements on the Regional Message Boards of other regions is not permitted. Minor violations of this should be handled by a region's Regional Officers; egregious and multi-regional violations should be reported via GHR for Moderators to handle.
Tagging nations (whether in Dispatches or RMB posts) for the purpose of regional advertising is prohibited.
*WA Advertising Spam: Non-natives and region-hoppers are forbidden to post WA advertisements or requests for proposal approval outside of their native region. The game-created regions (Listed above) are no exception to this rule. Requests for proposal approval may be telegrammed to WA delegates, but must be tagged appropriately. More than one request per proposal may be considered spam if the telegrams are materially the same. WA campaign telegrams shouldn't be sent to non-WA members. Tagging nations (whether in Dispatches or RMB posts) for the purpose of WA proposal campaigning is prohibited.
This behaviour is prohibited as it is considered evasion of TG filters that allow players to decide for themselves if they want to be contacted about recruitment or WA proposal campaigns. It has not commonly been attempted, as most players have the common sense to realise this, although a recent case has prompted us to ensure this is clearly codified.
This doesn't affect other common use of tagging nations in dispatches, such as regions which do so for the purpose of soliciting WA endorsements.
