d) Bot & Spammer & Content Creator is the correct answer. There are certain cases where a bot can server as the 3 of them bot I haven't seen that specific example, tho being a bot and content-creator and providing curation services seems like the winning combination for certain projects. I'm still debating how to classify @helpie as it is providing so much value that it can be content-creator and curator and source of knowledge. Thank you for everything :)
