I guess the question you are trying to ask is that can someone create their own customized tags and make

steemit add it to the list of tags available on

steemit.com/@tags which is the platform created for users to see the list of tags available on steemit,well if

you want your tags to be listed then it means you need to ensure that there are alot of quality contents using

your tags when posting on steemit,you need quality contents to use your tags because the more visibility a

content gets then the more popularity the tag will have,and when your tag start becoming popular then it

has a higher chance of making it to steemit.com/@tags....so that is why you need to focus

first on good quality contents because it is those contents that will bring visibility and even make your tag

to become popular and also your tag should be something unique and attractive enough to gain the attention of users on steemit....
