You can choose to flag with 1-100% if you have enough SP that it allows you the option. I was flagging at 1% for the last couple weeks, gently hinting at spammers to desist with the annoying shit. However, this seems to have literally no effect, as things are still escalating. So, now, I have been flagging at 100%, just as I vote, for the last few days.
When I flag someone, it negatively effects their rep if their rep is lower than mine, and just about every single spammer does have a far lower rep than me, so I am able to make their posts go invisible, UNLESS, someone with more SP than me has already upvoted it. Then my flag will simply remove some of their rewards.
well thank you for your explaination. because as you said in the other comment there might be one person hadling those account. because i see two exact user commenting on some of the other post almost at the same kind of time. and they are just doing it like tandem.
i might still need more time to see it again, but might flag them in the coming days if it is still the same.
It's very possible that they are controlled by the same person. But, I would do a little more investigating to ensure you're right before taking action.
If you're unaware, steemdb.com is a great site to explore past transactions on the block chain.
In fact, if you ever just go to the top of the address bar and change the "it" in steemit to "db" for database, it will take you to a page that will give you a lot of information on that blog/post/comment.
