You’re not using RARBG, you’re using the custom Torznab option, so no, there is no issue.
Unless you have an invite to a private tracker, none of them. Stick to English public trackers that have a TV category, e.g. 1337x, Demonoid, EZTV, GloDLS, ShowRSS, TorrentGalaxy (the latter being probably the closest replacement to RARBG).
