Generic Tags like "eos" and "blockchain" serve no real purpose as that is implied for all the pages here.
If these tags don't get removed from posts then we end up with the most popular categories being "eos" and "blockchain" for example.
"smart" and "contract" might be others to consider in favour of "smartcontract", people accidentally create two tags instead of one by using spaces.
Manually having to update questions every time is tedious.
Optimally this admin software provides some sort of tag blacklist where we can add these.
