I believe the skills and experience of campaign managers who run Twitter/X campaigns, Reddit campaigns, and other forms of social media might make them qualified for the skills and requirements needed to be a Social Media Manager.
Kinda different, the campaign manager could have already gotten the idea, draft, and others from the team project.Meanwhile from the jobs you mentioned, you mostly need to think by your self + several factors like editing skills and others. Some campaign managers, mostly have organization skills for the campaign but for the job's design like thread and other could be using other services. An example like HH: he organize many campaign, the design thread and other he using Jayce service.
I don't have any experience with customer service and moderator for casino sector, I only have with just common jobs for moderator Telegram/Discord.
All in all, not big win but a nice profit on my comeback after several months.
