I'm beginning to think that the editors are perhaps not completely neutral,
Some 200 of us can edit in any category that interests us - and we do. It seems extremely unlikely that we're all biased against your site (see below for the reasons why).
You might have misunderstood our objectives and how we operate here. ODP is a volunteer organisation building a directory as a hobby. Editors edit where they wish, when they wish and as much as they wish within the constraints of their permissions. We have no schedules or systems to force people to do work that they don't volunteer to do. ODP is not primarily a free listing service for website owners and it does not attempt to process their listing suggestions within the time scales desired by them.
Some volunteer will process your listing suggestion in time but we can't predict who or when that might be. Elapsed times can range from a few days to a several years. There is no need to re-suggest your website and doing so could be counter-productive because a later suggestion overwrites any earlier one.
We're resource limited here and one of our major problems is anxious website owners suggesting their sites to multiple categories (5 in your case - one of them twice) - thus multiplying the amount of work that our hard pressed and much maligned editors are presented with. Listing suggestions don't evaporate; they merely await processing. I find it hard to believe that you think there is a corrupt editor who sought out every instance of your website's listing suggestions and removed them all.
Please be patient and refrain from adding to our workload by suggesting your website yet again.
