Openly apologizing like this can be seen in many ways, both good and bad, some might even take advantage to write comments with ill intent, calling it a way to get attention and etc.
Now, from my point of view, as neutral as possible, I see no real point to you apologizing, most are stubborn to listen and what is done cant be changed. However, it is a very mature thing to do, assuming you do it mostly because of regret for your past mistakes, which is as well its own merit, for people tend to make mistakes and not care for consecuences.
Personally, this is a good sign of change and/or improvement, so i hope you keep doing well and improving yourself if you so wish to, but do remember we are in the internet and, funnily enough, in a Minecraft roleplay server, so dont take all too seriously and take into account some of the negative income can be critizism that can and should be used for improvement.
If anything, just ignore insult based comments, take constructive feedback into account and be happy to know there is still people who support you, even if with small things. +1
