As a fan of online literature, I have to answer this question based on the fictional story background. Here is some information that might be useful:
In some novels, data entry could be a useful profession. In some cases, data entry staff needed to enter a large amount of data such as historical records, population statistics, financial records, etc. The data may contain a lot of text and tables, which may be a challenging task for people who lack relevant experience. However, if one was interested in this and had some programming skills, then data entry could be a promising career.
However, it should be noted that the work of a data entry officer may not be meaningful in all companies and organizations. Some companies might prefer to use automated tools to process data without manual entry. In addition, for some fields that require a large amount of data, data entry personnel may not be able to provide sufficient skills and experience to do the job. Therefore, whether or not to choose a data entry worker as a profession, one needed to carefully consider their interests and abilities, as well as the current market demand and prospects of the profession.
You could also try self-publishing on popular platforms and monetize through subscription models or ads. But it takes a lot of marketing and building a reader base.
You could also self-publish on platforms like Amazon Kindle Direct Publishing. Earn money through royalties based on sales. Another option is to enter writing competitions that offer cash prizes for winning entries.
Yes, manga cleaners get paid. However, the pay can range from a modest amount to a decent sum, depending on various factors such as the quality and quantity of work, the reputation of the cleaner, and the budget of the manga production.
Getting paid for fanfiction can be tricky. You could explore self-publishing options and promote your work through social media to attract potential paying readers. But be aware that many fanfiction works are subject to copyright restrictions, so make sure you're not violating any laws.
