I dont really agree. Its a breeding ground for rrats yes, but I appreciate the transparency. If Cover beings to lie and make up excuses to cover up a suspension, and that gets out, they are in a much worse situation than they are now.
As always, cover doesnt need to adress the rrats (as they usually don't, unless they are Rushia-sized) and the drama around the suspension will die down. Covering up a suspension could potentially be much more problematic because it would destroy any trust the fans have. Every future vacation, break and visiting family will always be met with distrust, and no matter how real the break is, people will assume the talent is suspended.
And announcing suspensions like that is standard practice both in the regular Idol industry as well as wrestling. The rratposting so far has been mostly fun and harmless for Cover, so why should they give more details about a internal affair?
