I sure can. A campaign can be conducted in many ways but generally is done through social media as well as forums. You wont get bitcoins for participating but you will be rewarded
in the ALTcoin you are promoting. In general you do need a rank of JR to participate but some airdrops and campaigns do allow newbies to join. Ex. check out MasternodeCoin
In addition, you need to be careful about the rules. You need to post decent quality contents, and a minimum amount of posts to continue with their campaign.
Your rank will increase as you keep posting. It will take some time though.
Good luck
