In fact, we were confronted by the active contributor in Engineering Economy.
Maybe some of you will remember how we lost more than 3 months of posts and updates both from the admin and from the users. I think you have now a glimpse of how expensive to mitigate malicious bots online.Īnd for this site, we are hit faster than I can cope with, it suffered colossal strain and ended up truncating the database to remove all unwanted contents. For them to stay in business, they shift their service to enterprise-level only, yet, they still lost the battle and close their service. Unfortunately, the company that offered that service was overwhelmed with the needed resources to continue the service.
The spam technology we use back then was actually sophisticated at that time, it fought spambots so hard, very few to none were able to penetrate the system. In 2014, I opened the Forum and comment section to non-registered users hoping to make the community more active, and it did. After a month, I ended up with thousands of thousands of users (not-real users of course) with thousands of thousands of spam posts. I remember back in 2008 when MATHalino was hosted by Geocities of Yahoo, I opened MATHalino to accept a registration.

Until now, registration forms are the favorite of bots as the entry points of attack. Sounds great from the admin perspective right? It's now on auto-pilot! Actually no. When it comes to registration, MATHalino is a self-service site, which means that you are to voluntarily register and verify yourself for you to join us. On that site, I have not much difficulty in implementing security features to make it go the way it needed to. I manage another website that only site administrators can register users. In fact, the technical challenges are enormous compared to locked websites. Opening site features to as much as possible is great, but it is without difficulties. Those who wish to gain some insights on how this site is working and how we manage it may continue reading. If you are only interested in downloads, you can stop reading up to this line. You can find it at the bottom of the course outline. All future uploads then will be open to everyone.Īs of the writing of this post, all files for Basic Algebra Review Course are already available for download.

I will re-upload it all so that anyone can download it without the need for registration. Not anymore! The files that are already in the system will remain as is but this is only for a short while. Before, files for download are for verified users only. You don't need to register and log in to our site to access the downloadable files, take our exams, attend our courses, and participate in our discussions. No, you don't need to, but because you're a good person and you appreciate the effort put up by your fellow human being, you will.
