@Calehenituselover hi! Thanks for the spoiler, hopefully i can help with how to do the spoiler thing-y and how to edit the comment:
1) for the spoiler button its right over the typing box but it doesn't really say spoiler, it's just an eye and a crossed line over the eye but if you press it box with the name Spoiler! appears, just write inside this box (it's the left button, sometimes the eye itself doesn't show up, just white box then, right under stickers manga/anime for me)
2) if u want to delete or edit comments you go to the page where bookmarks, lists, history etc is and go to the one called "comments", choose necessary comment, press the button with 3 dots and there you can chose to edit or delete
