I LOVE your avatar! Don't change it. Beautiful. Goes with your username. Now, to answer your questions:

1) If you upvote someone, you are right. Sometimes your name will NOT show up. However, it is a good habit to get into, it brings good karma, and on top of that, if you happen to upvote someone early enough whose post does really well, it will bring you rewards. 

2) For noobs, it's pretty normal to say "follow me" and "upvote me" to one another. I think that's OK when you're starting out. You need to help each other out. I should have added that caveat. It's not BAD to do. Just don't do it to people who have higher reputation, or who have been here awhile. It will hurt your credit. After awhile, you will get to the point where you don't need to do that anymore. You have a reputation of 61. You should be fine not doing that at this point. 

3) Don't feel bad if you ignore others when they ask it. If they're asking you, they're asking everyone else. They are not going to remember YOU. You will not hurt their feelings. There are so many fish in the sea. You're just another one swimming by. 

I'm not sure what you were asking at the end, where "steemians blog where I found is not itself truth, it means I should blame to itself...."

Maybe ask that one a little differently...
