Due to conflict of interest WP:COI I will not edit biodiesel wiki pages going forward.
I feel that I have been convicted of self-promotion by attempting to put a link to my site back on the biodiesel external link list where it had been for several years. I feel that any objection I made was considered further evidence of that conviction.
It turns out the editor that removed the link actually supported its placement for years. I have specifically asked "what changed that warranted a change in status?" The editor has either avoided the question, or answered using an argument not supported by the guidelines.
What changed that warranted removing the link after years of supporting it?
