Today I newly registered an account on a Discourse-based forum. They allow only three likes per day (probably because of me being a new member).
Every now and then I accidentially click the (still clickable) Like button, only to see the blocking modal dialog box.
My suggestion is to remove this modal dialog box and replace it with something less blocking like e. g.:
- An alert tool tip like on Stack Overflow when trying to upvote after the maximum number of votes per day is reached (with auto close after several seconds).
- All Like buttons are automatically disabled when I hit the maximum numbers of likes per day, together with a tool tip that tells the reason why being diabled.
