You should post messages regularly. By doing that, you will increase your activity. You will be Jr. Member when you reach 30 activity. After that, when you reach 60 activity you will be Member. After being Member, you will need merits from other people to increase your rank. Activity will not be enough to increase rank.
That's exactly posted mate...Before the year of 2016 the day when i was joining here bitcointalk was really easy and fast to increase the rank from all of the member here..I am doing all of what you said mate, like a regularly posted a message here..then my rank is already up..and be careful of your post to avoid red trust. And that's exactly what i mean.
