Bulk remove Affiliates

I made the big mistake of using one of your extensions which auto create affiliates from existing users ( cant remember the name ).

This was a really stupid thing to do and now i need to remove them. I have been doing it one by one but with over 500 affiliates of which i need to remove 95% this is going to take for ever.

I need to remove all affiliates created on a specific date.

Is there anyway you can include a bulk remove, under manage affiliates tab, or is their some way to remove this.

I would be willing to pay for support to get this done.

Thanks
