Seems your ban was substantial given the number of rejected edits you were getting.
Edits need to be useful/worthwhile
On 20th April, you had:
That's not really a very good balance.
So I would also suggest as a friendly note, you should really look over your rejections and try to learn why you are being rejected so much.
It's welcomed that people help out, in fact it's one of the core principles the sites are built upon - community moderating.
But the help has to be useful and worthwhile.
Every rejected edit you get is reviewed by a bunch of users, and stored in databases, looked over by moderators and users with high rep in stats, etc.
So, please try to make them useful edits.
Is a tiny edit and very arguably "trivial".
In fact, it isn't actually "necessary" and the post is perfectly fine without it.
Have a read of these posts, they might help:)
Try to make the post substantively better when you edit, not just
change a single character. Tiny, trivial edits are discouraged.
A blog post by Jeff Atwood:
If you are going to edit a post, make sure you’re substantively
improving it. Avoid making isolated, trivial edits, as they are the
source of much friction. For example, don’t bother changing "its" to
"it’s" unless you have several other edits to make in the same post.
Some other questions/answers:
Why are trivial edits discouraged?
Why is editing so hard?
