Hello,
It appears that the original poster disagreed and disliked your opinion. A different member also disagreed, bringing the points to 3. The 4th point was an actual downvote and not a Like, Agree, Disagree, Dislike button click. There does not appear to be multiple downvotes from the same person. It's a combination of a downvote and usage of the Like, Agree, Disagree, Dislike buttons.
Keep in mind, any time a Like, Agree, Disagree, Dislike button is clicked, it also adds or subtracts a vote (Up/Down). Most members are not intentionally trying to manipulate the post voting system and simply using the Like, Agree, Disagree, Dislike buttons on the post to express their opinion regarding a comment.
Are you suggesting that members should not be allowed to disagree/dislike with other members opinions?
The incentive of allowing members to freely express their opinions (In compliance with the rules) as well as members being able to freely disagree with opinions (In compliance with the rules), is empowering members to self-moderate community content.
