I don't know how long and which auto-voter you used, but there's something wrong!
Let's take the example of the BeBlurt Delegation Program, something I'm familiar with as I'm its creator. This program returns 85% of the rewards to its delegators (while retaining 15% for BeBlurt development, including daily transfer fees and voting fees). If you delegate 40K BLURT POWER to @beblurt, you will receive a daily transfer of 8 to 10 BLURT (constituting the 85% share). Calculating the retained 15%, this amounts to 1.2 to 1.5 BLURT per day. Therefore, it would take 3 years to reach a "cost" of 1,400 BLURT (the transfer/voting fees part of these 1,400 BLURT is ridiculous considering @beblurt's 3.4 million BLURT POWER and the majority of this amount will be dedicated to the dev of BeBlurt.). However, during that same 3 years, you would receive 10,000 BLURT.
