Reporters are allowed to use hashtags in the same fashion as any user on Twitter.
This does not appear to be a question about the use of the Twitter API developer platform.
Please use help.twitter.com for queries like this. This forum exists to help developers with API questions.
We cannot offer any assistance with issues related to accounts (suspension, verification, usernames etc), or usage of the twitter.com website, analytics or ads dashboards, and the iOS and Android mobile apps in this forum
