what happened 2 months ago with steemit?

1 so what really happened 2 months ago... as i go through most profiles they stopped their activity two months ago..... its rather strange...
my guess is that most profiles were bots operated, then something happened and they stopped two months ago... can it be they will be reengaged sometime in the future? and post millions of posts at the same time? can it destroy the universe?

2 and another question, what is plankton badge and what it represents here on busy....

3 and another question, how to raise reputation score.....

4 and how to log out from steem it... once i pressed always remember in logon function.... and now i cant find where to log out.... so i could log in with different key.

5 and how does one voting power increase?

content, flourishes as it is being created. and it needs to have a medium.
and i do need your help, so support the effort. thank you.

kindness is the first rule.
have a great time.
