1. The reverse effect. The merit-system was made in order to save the forum from the influx of useless posts, topics, etc. Today, "thanks to" the introduction of this system, we have the following: the creation of the same topics about new merit system, about shit-posts and the emergence of begging.
Keeping in mind how this new system affected the members here, I think it is obvious to expect so many threads. Also, this is not permanent. As people get used to this, we will have less of these threads.
5. Get-away. Many participants can make a decision to leave the forum, observing the current situation and the forum will be empty. The bottom line: on the forum will stay only "oldsports", but some people don’t understand, there are some newbies who benefit the forum and share useful information. If he is newbie on the forum, this does not mean that he is newbie in the field of crypto currency. I know many crypto-guys who into the theme of crypto for several years, but have not been registered at the forum or registered recently.
If you are knowledgeable (irrespective of your current rank), you should be able to make quality posts. And if you are making quality posts, you will get merits and rank up.
