Most of everything is allowed; tech-related or kitchen-thingamajig. If it is to help with the development of knowledge or the overall well being of the community it is fine.
I wouldn't say discussions related to stressers would be 'illegal' per forum rules but are they developmental. most of the 'stresser' posts we get are advertising their stresser/booters which is something 90's ish.
But if you are discussing, howto; code one, persistence, using and utilising server cores and resources, case of target-firewall blacklisting what next, blah blah. Which as you can see is networking, sysadministration, coding techniques, blah blah and it so happns to be th usual things posted here or even better.
So, if you aint advertising one but actually talking about architect or technical stuff related to it, i think it would b fine.
