Choose to do self like or not

[VickPix]

If in the latest posts there are own images, then the script will like them:

// Decide to like post
if (hasEmptyHeart !== null && Math.random() < cnf.settings.like_ratio) {
     ...

But if there is a control for the username this will not happen, for example:

// Decide to like post
if ( username != cnf.username && hasEmptyHeart !== null && Math.random() < cnf.settings.like_ratio) {
     ...

Is it correct? Or it doesn't matter?
