Got rid of this so as to not make the site glitch out - thank you to the posts below for explaining to me the difference between aliases and implications

Implying A to B means that A will atomatically result in B, but the inverse isn't true; in another hand, aliasing A to B means that A and B will act as a single tag and B will be the one used to representate both.
In that case what you should suggest is an alias, however we have a bug which impossibilites to suggest an alias to two tags already involved in an implication suggestion and viceversa; So I would propose you to edit your post, strikeout the previous suggestion ([s]text[/s] → text) and write the correct one below.

Above post paraphrased:

• Implications add additional tags one-way
• You want both tags to be interchangeable both ways, which should be an alias
• Please remove your implication request before making an alias request because e621 glitches out if you try to imply and alias the same two tags

They can't remove it, but they can edit the text in and request the alias instead.
