Unless it's against Lemmy TOS, why not?

My typical method of checking is to look at the mod log at the very bottom right of this page (next to Legal), and search for their name. Activity there does not rule someone out, especially bans from .ml, but it'll help you make a judgement. Then I'll spot check their history, both for content and how often they post. People who are going to be on the site regularly anyway tend to be better moderators, as they'll both notice their notifications and spot things without being prompted.

Unfortunately, tech_memes is still too new to offer any suggestions on who to pick. The one name I do have I'd quickly rule out from my previous interactions with them (likely troll).

Generally moderating a community shouldn't take more than 5 minutes a day (a little more some days, a little less most every other day). It's part of the reason we try to find a lot of moderators to do a low number of communities each. Hopefully you're not getting that many reports on different content.

If you're still having issues, reach back out to us in a week or two and I'll see what I can do.

Thanks,
