I have been asked to reply to concerns, thus i am writing this post to compare both platforms.
In essence, both platforms have different approaches for rank upgrade and thus as a result on signature campaigns.Let's start with Bitcoin Talk ranking:- In the past, BTT limited the number of rank upgrades to roughly once per month, thus you can rank up once per month if you are active.
- Now, BTT changed the rank system to base it on "Merit", means you will only rank up once you get the needed merit points - not easy to achieve, thus locking the average joe in lower ranks.
Altcoins Talks Ranking:- In the past, we had no restriction, except for some sections where we did not count the posts, users were able to rank quite quickly. This was also true for BTT in early days.
- Now, we have implemented a system to ignore non meaningful contributions, thus ranking became harder as much more posts are no longer taken into post count .
For a signature campaign:- BTT puts limitation on signatures based on ranks, and does not allow images.
- We do not limit signature based on ranks, and do allow images, thus you can create 1 signature for all ranks, or even better: you can create an image or gif signatures!
Further advantages of ALTT:- We try to detect duplicate accounts, and immediately label them as duplicates, thus helping you avoid being cheated.
- We will promote you bounty, just donate some tokens to our forum account, and we will help you reach more bounty hunters.
- Your bounty will be more visible, as it will stay visible on first page for several hours

unlike BTT where the amount of competition and spam posting will bury most campaigns limiting your presence on the sub-forum 1st page for less than 2 minutes.
