Creating a totally Useless build up
Further to answer of @RayMairlot, another thing to consider is the hosting provider.
Policy for linking to blend files
Should all "Ask A Question" pages encourage the poster to upload their blend?
Often see a comment request to add a blend file to a question. The suggested host is often http://blend-exchange.giantcowfilms.com ie permanent blend file hosting for bse provided by user @GiantCowFilms. Similarly with those attached to answers.
Often the answer is change this setting, or plug this node in here, not here ,, As far as the Q&A is concerned there is no need for anyone else to DL the blend. From this point in time the blend file does nothing more than take up space. As we are aware from our download, pictures, desktop and other folders that grow and grow and grow some maintenance is required, or provide more and more storage space. (HD's have grown from Mega to Terra in 20 years, doesn't take 20yrs to fill them)
IMO In many cases using a temporary service like https://pasteall.org/blend/ would be much more suitable. The blend file is kept for around 5 months. Generally if the question is answerable and someone has requested the blend it is answered in less time than 5 months.
Could add a zillion links to questions / answers where I feel a permanently hosted blend file is totally unnecessary. (Sure you have seen plenty) Does it matter if the link to blend is broken. How many answers over 5mths old even get looked at?
To sum up, consider requesting user upload blend to a temporary hosting site
