Returning to old account after years of improvement

Hi there, 
The is kind of an odd question but figure I should ask in case someone here has some advice. 

I recently reopened an account I closed about 3 years ago (this one). During those 3 years I would start and stop playing chess on other websites while continuiously improving. 

Now I'd rated around 2000+ on another site and decided to give chess.com another try. 
My worry is because of my improvement my rating will probably double from where it was when I reopened this one. 

I also bought a membership, and I'm just wondering is there someone I should reach out to about getting my rating reset. Or if my short term increase in rating flag something in the system. 

I'm just worried I might getting wrongfully banned after buying a membership. 

Any advice will be great. 

Thank you,

If you're playing fairly you have nothing to worry about.
