Fortunately, they can learn before their accounts are blocked or the wiki is nuked. The latter is a real outcome, seeing that Fandom has been closing down wikis due to their unruly users (messages like this one are not acceptable). If things went on, Discussions closure could be the least thing that would happen... and, seeing the edit-to-post ratio of those on that thread alone, it could be for the best.
Amusingly, your own name could be seen as wonky on Spanish-speaking wikis, as "viola" is not just the name of a music instrument, but also "he/she/it rapes" in said language. If, for example, you edited around a Pokémon wiki in Spanish and your username was "ViolaPikachu7", chances are you'd get blocked due to a lack of context.
Obviously no.
I, too, know of wikis that block users (usually before a warning, as some don't do it out of bad faith) whose names include mild vulgarity. How mild, you may ask? In case you're interested, I remember a case in which the username was something like "Poopybutt".

It was a bad joke, as the term is "blocked".
Accounts aren't banned either :P
They are not here-hence why I adviced you to contact them.
If that's the case, contact Fandom and explain the whole thing to them. Remember you are to back up any claims with links, not screenshots.
The profiles (well, message walls) are at community.fandom.com/wiki/Message_Wall:username
Contact Dandy's World local staff (you can message them on this wiki) and explain the whole thing to them.
You created the thread hours ago. People have lives of their own.
You can keep on using the same thread, you know.
People often know better than edit warring for years.
You can contact those people via their respective profiles on this wiki.
Tell said people, not us. If you have any abuse issues, contact Fandom with links (not screenshots) to back up your claims.
It comes handy to Google the user up if said user has a generic name.
If the image is on a wiki (why would you ask here otherwise?), check whether said image has its license stated anywhere. If it isn't, and the uploader's around, you can ask that user: more often than not, people won't use the correct license or will leave it blank.
If the reply is "no idea", you could use a reverse search tool, such as https://imgops.com/
And you won't find that here. You've contacted a local admin -who has not been around for ten days- so you should just wait. If said admin did give you a reply elsewhere, it'd be nice to know what you were told. Generally speaking, admins should ensure all users feel welcome and that the wiki has a good environment for edits to thrive (and for Discussions to be civil). Speaking of Discussions, you should not use it for this, as it often breeds drama.
Also, it seems you may not have told us a certain part of this story.
As a partial aside, I have the feel this wiki is no stranger to drama anyway, seeing that, despite having only been around for a year, it has SOAP Bot around and interventions by Fandom staff and related echelons.
"So if, in case a listener would type my name, it would appear in Google search."
I don't think Fandom allows SEO gaming. Furthermore, it could be seen as advertising, which is forbidden by the terms of use.
