Locate the line in the OssnAds Component, remove it (or better make a clone of the ads component first and remove it there) and you're done.
Due to the many requests in the past for additonal features and components we have decided to develope a premium version. Features like Hashtags, Videos, Polls, Events, Stories, Link Preview, etc included in it.
