As we have already observed, DDoS attacks produce different effects on programs and their administrators. In some cases, they damage a fragile program stability, making it crash. In some cases, they encourage admins enhance their protection and improve technical performance. Looks like Wlinv refers to the second type:
BlockDos' business could be explained as "unethical, immoral extortionist".
In spite of our repeated requests, BlockDos is yet to provide any verifiable detail of last DDoS attack. However, BlockDos never missed an opportunity to extort more money in the name of DDoS protection upgrade.
Its even interesting to note that they always escape to answer the questions like "What are the specifications of new upgraded protection?"
Finally, 7 days back they terminated hosting of site because we haven't upgraded (no rational being would ever buy a service or product without knowing what exactly is provided), with a small notice of just 12 hours. More interestingly, they have promised to refund the fees charged in advance for service which wasn't used and its already been over 6 days with no concrete reply from them.
Anyways, we are shifting to Staminus Communications very soon. Our protection under Staminus's Ddos protection is 1.2 Gbps.
