Blacklist plugin

[LillianA]

So I'm making a blacklist plugin (As seen on 90% of HCF servers if not all of them),

What type of things should I ATTEMPT to include in the plugin (Storage types mainly but I'll take other suggestions.)

YAML storage will be the default storage type.
MySQL is also planned but,

Should I add something like Redis or MongoDB (I'm not too sure what most people use anymore I just stick to MySQL)

The first release will *hopefully* include MySQL + YAML storage types and if I feel like I'm spending to much time on the MySQL end of things I'll just release it with YAML only for a little then update when I figure things out. I'll be releasing the plugin .jar along with the src (Not GitHub cause I don't have administrator on my computer)

Note: I am still decently new to both Java and plugin development since I basically started to learn both at once and I've been messing with Spigots API off & on for around 3 months now but more recently in the past week or so (And when I do release the SRC please give me constructive criticism on my code and tell me ways I could potentially improve if you're going to criticise me for it.)
