Here is the direct answer from forum admin,
Most giveaway threads are no longer allowed in the Alternate cryptocurrencies sections. From now on, posting or replying to such threads could result in being banned. Existing threads will be locked.
Specifically, you are not allowed to give people any incentive to post insubstantial posts in your threads. You can't offer to pay people who post their addresses, usernames, etc. You can do giveaways off-site and link to the giveaway page in a thread, but you can't give people any bonus for replying to your thread.
Similar threads are already restricted to Games and Rounds in the non-altcoin sections, but the giveaway-related post volume is so high in the altcoin sections that I've decided to just ban them entirely here.
Summary is you can't ask to post on your thread in order to get giveaway payments. If you do so you and who replied on your thread will banned from forum. You may add ad a link of google spreadsheet or something similar to complete your giveaway task and report there.
