Argh.
I am backend web dev, which has nice software developer role, with later going to dive into devops a bit more.
And yet some people don't understand when they are told No!

I will not accept being hired for short terms job of sysadmin.

To make it worse it is offered by my mother.
She works for some person who has multiple web sites, and they suffer from some sort of attacks.

I am having no time for this. I work and learn 95% of my time.

I don't care what they offer. According to what I heard she works for corrupt person, and she already offered illegal work few days ago to me.

Thanks, no. They deal with too big sums of money, I dont wish to be arrested or killed. I have a good job, planned schedule for next half of year and my own life.
