My thoughts about this, long story short, no matter how many downvotes you give to these people, they are still here, still spamming and scamming, advertising services that (I'm not sure) are good. Even if their reputation goes below 0, they still can post. I've seen reputations like -11. No one stops them.
So if I'm downvoting them, I'm practically giving up my power to help others grow. And what do I or we get in return? Absolutely nothing!
As about your links, they might be legit, but with all that phishing and scamming going on here, let me be suspicious and not click any link from someone I see for the very first time, even if your intentions are good and the links take to Steemit.

I appreciate your effort but downvoting is not the answer, not for me!
