No

I really don't think the people who get less from upvotes does so as a result of where they post from

One can use the tag or the frontend and still earn more or less depending on those who upvotes him or her

You see, when curators vote posts, they have a certain percentage so their voting power doesn't drain quickly

That means your rewards on a particular post depends not on the frontend, but the power of the human voting you

If his stake is worth a lot, and he adjusts his curating percentage to suit him, then, you get whatever the equivalent is in a particular token

Take for instance, if you use other tags in your posts alongside POB or LEo, you may discover that once you view your account from different frontend, the amount you get is different

You may receive let's say 174 votes as you just did as at the time I wrote this comment.

Watch, this post may not have lots of POB as rewards but may have lots of Hive/hbd rewards instead

That won't be anyone's fault, it all depends on the amount a particular vote gives you

The next time you want to feel bad the amount of POB you are receiving, cross check other tokens, from different frontend, the difference will be clear

Watch this screenshot below

See what I meant? You have accumulated up to 8hive rewards for the number of upvotes yet, less POB

I really hope you understand

Oh one more thing, I do not think, it's your fault that bad things happen whenever you join a particular venture

Please, scrape that thought off your mind
