Unlock limits are placed to prevent leeching. Regardless on if someone has purchased a rank or not, they can still leech.
Reputation power is fine. You don't necessarily gain OR lose anything from the amount of reputation you can add or remove.
Think of Supreme as the rank you get if you want a good price for some forum perks. Divine, while having 3 additional perks, also has access to early access changes.
You're bitching over something that's been in place for YEARS. Yes, others may have complained about it but a GRAND majority of members don't have an issue with the current upgrade pricings. You don't seem to understand, but that's a main income for forums, and hosting a forum this size isn't cheap. Given what is available to unlock AND have access to, the prices for the upgrades are honestly generous, they could be higher given all of the data that's been shared on here over the years.
Also, I will slightly agree that the like system should have functionality to remove the like if placed by accident, but either it wasn't added intentionally for say, spamming capabilities, or it was simply overlooked.
