unfortunately you do not link to that twitter (or any social media) from your website, and the twitter account is brand new as of Jan 2020 so honestly that doesn't actually help prove you are the content owner. Anyone could have made that twitter account and the fact it was made right around the same time you started posting on Steem actually makes it look a little suspicious.

EDIT - thanks for the confirmation on Instagram. :) https://www.instagram.com/p/B5DcHQRA6he/
If you want to avoid having people continually asking you if this is your content here, the easiest way to do it would be adding a link back to your steem blog on your website. If you don't want to do that for some reason, adding a link to your twitter on your website would verify that the twitter account is actually owned by the real Zimer :) A verification on Instagram would help as well since at least the instagram @zimernyc account is older and has 7k followers, so much less likely to be faked - but note you do not even link to your instagram from your website either.
