I will exagerate and ask you: are you discriminating between bigger and smaller instances? While smaller instances are definitely small, together they are big enough.
They could have done nothing, but because someone on a so called trusted source de-federated it because he did not like him, de-federation would accumulate.
Actually beehaw is a nice instance and is blocking lemmy.world, which too is fantastic. Thus sharing beehaw's de-federation list would cut out lemmy.world from a huge audience. In this particulare case, I wonder what lemmy.world did wrong to be worth de-federating from.
So you see, sharing huge block lists would wrongfully cut out people. Since nobody would investigate the whole list because doing so would take weeks.
Joining another instance is out of the question for many because they are firm belivers of self-hosting and decentralization. Two principles that are pillars of the the fediverse.
Seeing the number of down votes I may say that most people do not take smaller or single instance users that are too common. They are the ones that get most hurt with shared defederation lists. This only encourages people to gather to well known instance or accept being cut out from the biggest part of the fediverse.
This is when degeneration is used with sanity. However, people just use that feature to cancel people they don't like. And this hurts smaller instances a lot.
You forgot people who selfhost single user instances. So they would have to destroy the old instance and create and new one with a new domain, which is a lot of work and resources.
Edit: Please also notice the problem here is not defederation itself, but shared lists of defederation. Because most likely the list is super long and nobody would check if all instances are legitimately blocked.
There are anti viruses that run on GNU/Linux like ClamAv and kaspersky but they actually do not target the machine they run on or at least they are not so useful. Their intention is to stop the spread of malware.
In general, you just need to install softwaref uaong the package manager from trusted sources that are usually the defaults of your distribution and not input your password when you are not expecting it.
When copying commands to the terminal, most terminals will warn you if you are copying a command that requires root privileges.
That said for the operating system, apply it to the browser as well by being eclectic on what extensions you install and voila. 99.99% guaranteed malware free.
It is not wrong to choose animals based on colors. In ornithology this is a big criteria in bird selection and pricing. For example, there is a whole category of canaries based on their colors. Other small parrots have been bred specifically to be of some color or color mutation and it is a big factor on bird price. This is also very common to choose dogs based on color when the breed has many.
Instead of a script try the command directly in ExecStart. Systemd should take care of keeping the process running without you having to do nohop and disown.
If you insist on using a script you should use a full path to sh or bash with the path to your script as an argument like
ExecStart=/usr/bin/bash /path/to/script.sh.
