To ensure quality of advertisements are high and that others don't stumble upon errors such as invalid invite links, we have AYS AdMod which is a bot that undertakes the task of removing hundreds of ads per day in the server which may trigger it. This article can be particularly useful as to why your advertisement may be deleted by AdMod.
Your advertisement must include an invite link
This is typically obvious, your advertisement has not included a Discord.gg invite link. Other types of invite links (e.g. dsc.gg, invite.gg, discord.io, etc) are not supported due to the nature that it can't be picked up and validated by AdMod.
Your advertisement contains X invite links but the limit is 1
This means that you have included more than one invite link to a Discord server in your advertisement. If you need to include multiple invite links in your advertisement, we would recommend sending out separate advertisements for each separate server.
Your advertisement contains an invalid invite
This means that the invite link you have input in your advertisement is invalid or isn't never-expire. We delete advertisements with invalid invite links so when others look for servers they are interested in, they are not met with an invalid invite.
Your advertisement contains X characters but the minimum is 150
Your advertisement is too short. To allow for more higher-quality advertisements to be posted (for the user to gain a better understanding of your server), we have a minimum character limit of 150 characters. Please ensure your advertisement not shorter than 150 characters and re-post it again.
You already sent X advertisements today. You may post more in Y hours
You have sent the maximum advertisements that your limit allows you today. Please refer to our Advertising Limits help article for more information on advertising limits as well as how to have it increased.
Invite rewards are strictly forbidden in AYS
This means that invite rewards has been detected in your advertisement, which is not allowed on Advertise Your Server due to the fact that these servers are of spammy nature and sometimes breach Discord Terms of Service.
