Hey there, I'm pretty sure wikis only close if they break the Terms of Service. That being said, I would recommend you just forget about it for the time being. A user might pass along and want to adopt the wiki.
Once wikis are created, they generally won't be closed. If you are not interested in your wiki, you can leave the wiki inactive so someone can come edit if they are interested, or someone will adopt your wiki if your wiki is becoming very inactive. If you believe your wiki is terrible, you can just delete everything you have done, and set back to default.
Or, if the wiki becomes too inactive, it will be closed itself for inactivity.
Heya! That image is a bit outside of the size needed for background images. I'll look into editing it into the correct size tomorrow. For your reference, we have a template at File:Background template.psd. Thanks!
I also see you've been editing the wiki a bit recently, are you perhaps working towards adopting it?
Hi Tya! I would just like to ask if we can get help in the Bungo Stray Dogs Wiki. I just became an admin for the wiki and there are actually a lot to change and improve like doing a revitalization, currently we only have two admins and a wiki manager. I saw you on MHA Wiki and I though I could approach you for some help. Currently we need to arrange the image galleries and character pages since they are not up to date and lacks information. I would appreciate it if you could give suggestions. I also want to approach YoungMako since he is expert when it comes to images. Thank you and have a good day!
Hello! What you can do to help combat the troll is to continue to report them to VSTF so that they can be gblocked. Also, do not engage with trolls is another great thing to do. They thrive off interaction and want to incite anger in you, so if you see them on a wiki you have admin powers on, just simply block and delete.
Drawing is something I've been wanting to practice, but I wouldn't say I'm any good at it. The biggest tip from everyone I've seen though is to just keep practicing, look at art you like and try to figure out how they did things. You will draw bad things, but through practice and refining your skills, you will eventually draw good things.
Thank you for your help. By the way, this is not the first time this happened in an identical manner. It has already happened yesterday and the day before. A total of 5 users were involved and with this one it is 6. Do you know who they are?
