Can creating upto 300 user roles affect my site

Do you mean 300 users, or 300 unique custom user roles with their own individual capabilities? https://www.ads-software.com/support/article/roles-and-capabilities/

300 unique custom roles, just like using the user role editor plugin to create additional 300 roles,maybe making a copy of the subscribe role into 300 versions with different role names.
Am not talking about creating users.

300 user roles but the capabilities will be a copy of the subscriber role, something like subscriber1, subscriber2, subscriber3 till 300

Well then you won’t need 300 roles then. ??

If the capabilities are all a duplicate of the Subscriber role, then you just need 300 users with the Subscriber role, and there’s definitely no problem with that.

This site in particular has almost 2 million users with the Subscriber role.

Nop am not talking about users having same roles, my site have a function and access i like to treat each user role differently. My sjte currently have 100 users in the subscribers role but that’s not what am talking about, i need 300 roles in my site and perhaps each role can have more than 500 users in a particular role. Lets say am having 500 registered users on my website and i want to split them into 300 different roles.

SO MY QUESTION IS DIRECT AS I ALREADY KNOW WHAT I WANTED, CAN HAVING MORE THAN 300 ROLES AFFECT MY SITES IN ANYWAY?

Then you’d better direct your question to the support forum for the custom role plugin you’re using, it all depends on that.

And, honestly, shouting isn’t really appreciated here. It’s ok for people to misunderstand you, but it’s kind of a dick move to yell at them for it.

Thanks
