It seems that because twitter recently tightened their rules and caused trouble when locking up a lot of crypto-related accounts, people were more interested in new social networking projects.
I'm using a social network similar to Blabber is Empowr in the past few months. Although they are pretty good, they still can not eliminate fake reputation, and spam.
How does blabber solve two problems fake reputation and spam?

Hello, phucdigan and thanks for your question.

As one of our core features, we have integrated a mechanism to ensure a secure and transparent reputation for each individual user. BLABBER calculates a dynamic "karma" for each user, based on interactions within the network and interactions with the users content through other users. Different on- and off-chain metrics such as collected and granted rewards, the number of posts and comments and their respective quality, as well as received likes and troll votes are used to calculate a user's karma.

Karma has a profound impact on the visibility of a users content within the community. In particular, "troll votes" can significantly reduce the visibility of new content of a user who has received the votes. An important factor in troll voting is that a vote is always associated with a certain strength, which in turn is calculated from the karma of the user who casts the vote. For example, a new user's troll vote has very little to no strength and cannot be used to intentionally harm other users. At the same time, the troll vote of a user with a high reputation has a much greater impact within the community.

A cooldown interval will be implemented to circumvent "troll vote" power abuse of users with high karma (high "troll vote" power). During this interval, every "troll vote" will become less and less powerful than the one before. All "troll votes" in the said interval will be included to calculate the power of the next "troll vote". The user must wait for the interval to pass to regain full "troll vote" power. Although the "troll vote" power decreases with every additional "troll vote" of a user, the "troll vote" power never becomes zero, but converges to zero.

The BLA Token, therefore, plays a central role in calculating a user's reputation and in this sense represents a utility with which reputation generation is made secure and transparent. With this mechanism, we will create a "self-regulating" community where users impact the relevance and visibility of content by means of their interactions and therefore are able to prevent spam without the need of a central authority.
