Better use your signature well in promoting your own link/discord server. Most users in the forum would not trust a Newbie account to make them earn crypto just by using discord, hence work hard a little to somehow make a valid and reasonable account for people to trust. Even so, you should also keep in mind that the action you are talking about doesn't break the forum's rules as long as you post your single and own thread in Services section (to be specific) and promote it there alone, meaning that you shouldn't spam links on your posts pertaining to the said server.
