Ok, got your point. I will not use sports talk tag anymore. But, here is the thing, I saw people posting in cine tv & other community, using hash neoxian, hash creativecoin hash proof of brain, at the same time. So what happened, nobody talked and remarked for using multiple community tags in a single blog. Hope, you also saw that.Its pretty natural to use community tags as other users also use these tags most often. I just followed them. But, if this still bothers you, I wont use the tag anymore, problem solved.
But, why did you said about tag abuse, If I dont use the tag, nothing will come and go, but saying strictly that I used the tag abusively spoils the respect of my blogging.

Sorry to say,that this tag bothered you but its ok, my request to you to see other posts using multiple community tags.

Thanks well.
