Secondly, even if my BB thread is gone forever (and I pray that it isn't), I would appreciate it if y'all would add a confirmation prompt to the deletion of BB threads, so that this sort of thing never happens again in the future. (That thread was my first BB thread, and it meant a lot to me.)
If I press the ✘ button that is for deleting blog comments, even in my O2DS's browser, it'd bring up a popup window that says:
3dspaint.com says
Delete comment?
Cancel OK
Now, I just looked at how you delete BB threads, and I see that it is actually a box that gets checked, and you delete the thread by checking the box and hitting the "Submit" button, similar to how you currently delete profile pages and group pages on here, as well.
IMO, this is a VERY bad idea for any of these things, because if you accidentally check the box due to lag or being distracted, and don't notice, you could easily delete something that you are working on by mistake (like I did), as the button simply says "Submit", and no confirmation window pops up like when deleting (or flagging) blog comments.
If it would be possible, replacing all of those deletion checkboxes with ✘ buttons that trigger that simple popup (unlike the ✘ buttons for deleting DMs or for rejecting group invites, which don't currently ask for confirmation either) with a "Cancel" option and an "OK" option would be ideal, as well as adding that same popup to all ✘ buttons that currently don't bring it up.
(It shouldn't be easier to delete an entire BB thread by mistake than a single blog comment.)
As for recovering my deleted BB thread, unless someone here knows of some online archive that actually has a portion of it (which is unlikely), then I'm not going to worry about that RN.
