Something like what @dkbit98 suggests could be used for mixers, for example, (although it could be used with other products) that way users who visit the forum would not have to copy the URL or have to search in a search engine, where there are many links to phishing/scams. The link would always be the correct one without the possibility of writing it wrong or having to remember it.
For other types of uses, other than signature campaigns, as we have mentioned, it is best to reserve this function for high-ranking users.
