I think maybe you voted for a proposal? There are sometimes requests in the comments to support this or that proposal.
I'm not sure which front end you use, but in PeakD, if you use the drop down menu under your account name, you'll see "witnesses"; click through and it will take you to the list of witnesses.
You can choose who you want to vote for from the very long list. You have up to 30 votes, but I don't use all of mine.
If it is all a bit much, you can set a proxy which means that your votes will follow the votes of the account that you set as proxy. This must be someone you trust 😁.
I see. Thanks for the information @shanibeer.
