This is a different point entirely (and also one I disagree with). Limiting SSL certificates should NEVER EVER be done, however limiting connected domains can be done (I think this is an MOFH option if you want to do it yourself), but it just makes the free hosting platform even less usable, so strong disagree.
Don’t ever do that again. It’s advertising. If I was a mod here I would petition to give you a final warning on the subject, with a future violation being an immediate permanent ban. It’s incredibly annoying, unwarranted, etc. just post your post and I’ll see it when I check this forum (Which is usually every other day or so).
