You're doing a good job curating quality motorcycle content in your blog! You made it easier for people to find quality motorcycle content at one spot.
About the tag, I thought so too. We can keep using #motorcycle only if we get rid of spammers using that hashtag and I don't think downvoting them is a good strategy to make them stop using it. I have been commenting on their posts and asking them not to use it. Seems like it has been working so far.
Thanks for commenting! Followed you :)
