Although they don’t obstruct development, there are some that shouldn’t exist in the first place like: #scripting, #building or #modeling
There are tags which are too general, and on top of that they already have a category that includes them completely (examples that I gave before). Although its true that there are others that can help someone searching for topics by tag like: #httpservice or #terrain.
There are many that can be obvious due to their category. Here is a list of ambiguous tags (by category)
- Scripting Support and Code Review
#scripting, #code, #lua - Building Support
#building - Creations Feedback
#feedback, #creation, #creations - Resources
#resources, #tutorials - And others than don’t make sense
#help, #i-need-scripting-hel, #randomtag, #why-roblox, #problem, etc.
Although there are more, I’m not going to bother looking at every existing tag.
