"I don't like to be forgotten"
Examples of being forgotten:
- You spent time with someone, but they had to move and come back two years later and they don't remember you.

"I don't like not to be acknowledged" -> This sentence should be "I don't like to be acknowledged" or "I like to be acknowledged"
The reason why this statement isn't correct is because you can't have "don't" and "not" together because "not" cancels "don't".
"I don't like to be acknowledged" means that you don't like it when people notice or say hi to you.
"I like to be acknowledged" means that you like it when people notice you and say hi.
If you are acknowledged, you aren't ignored.
I hope I helped! Your grammar is pretty good! Keep up the great work :)
