I always try to post the same amounts on all boards but indeed, I am posting a lot in the Altcoin section lately because of the Envion scam claiming process and that I keep managing Investa ANN thread from the beginning, as I promised to the team. They fulfilled all ICO promises and I will keep mine. Additionally, I am invested in a few altcoins (bounties, airdrops, ICO investments) and that is why I keep attention to their ANN threads.
Additionally, I can post in many local groups if there is such need, already trading for almost 15 years (forex, binaries in the past, crypto from the beginning) and have a lot of experience, but don't post in the trading board because I already post a lot. There are many other boards on which I could easily start to write taking into consideration experience, knowledge and hobbies, that is why I ask for your opinion and advice.
It kinda looks like you are trying to change your postings habits to match the campaign... That usually doesn't go too well... It would be better to find a campaign that suits your natural posting (without any paid incentive) and not the other way around...
