if users delegate to other accounts they don't get your vote

correct,

This is because of my javascript limited development skills, however I have nothing against curation groups that don't operate on a delegation/upvote basis.

This is the code that I'm using to detect delegation. Once again, if someone can fix this code to omit curation groups (accounts) approved by me, then authors delegating to such groups will get automatic votes

//connect to a steem node, production in this case
const client = new dsteem.Client('https://rpc.blurt.world');
const delegator = author;

    var delegationdata = await client.database.getVestingDelegations(delegator, "", 1);

delegationdata.forEach(newObj => {
name = newObj.delegatee;
shares = newObj.vesting_shares.substring(0, 1);

});

if (delegationdata[0] == null) {
shares = 0;
console.log("delegation: ", shares);
sleep.atomic-sleep(1000)
}
else {
console.log("delegation: ", shares);
}

and then

    else if (shares > 0)
        willVoteFor = false;
