First of all, I would start by reading what merited users are getting merit for. I’ve looked through your post history and they are nearly all bounty posts. Bounties are not going to give you merit, so you are going to start to move in a different direction for it.

Check for example TMAN’s guide to getting merit (https://bitcointalk.org/index.php?topic=3182178.0). Don’t just read the guide, read through the whole thread to get a better idea.
There are many more posts giving experience such as bitmovers: https://bitcointalk.org/index.php?topic=3306385.0;topicseen

Check the general stats here: https://bitcointalk.org/index.php?action=merit;stats
Look through posts awarded with merit and get the general idea of what it requires.

In general, concentrate on bringing content to the board and not on activity. Less posts with more content is way better than a trillion empty posts per day.

P.D. Russian Board is by the way very awarded as a local board. Check zentdex’s post: https://bitcointalk.org/index.php?topic=3093768.msg31934877#msg31934877
