Welcome
Now we know some people will nag you abotu reading rules. I would say it is an easy msitake to miss the area which they require from you. I'll explain why tis easy to miss it:
Rules are listed via numbers.
So when you read the alst number and attached rule, its easy to click back or 'forum home' etc.
Also, the part which they require you to read is also marked in such a way that from a sideway glance, can look as the lining which soemtimes may make it appear as a signature above the pics of soemones profile signature.
So is it suspect that people are missing this final rule? Or just simple misunderstanding of onyl reading what is numebred and missing the final parts cause it kinda looks like something else unrelated?
I think both are highly possible.
