The questions linked to in the chat conversation were garbage. The very definition of the kind of content we don't want here, and what delete votes are for. Example:
I have this link
I want to replace this part:
&w=120&h=120 with a blank so i would have just
I've tried with str_replace but no luck. Any ideas? Thanks!
As to targeting questions that you have answered - I don't think anyone is attacking you personally; but even if it were the case, then it's just you answered a couple of exceedingly localized and basic questions that someone maybe found through your profile. I don't know, but even that would not be a problem in my book. Answering crap is not a sin as such, but I've arrived in the camp that says answering these kinds of questions encourages the asking of even more of them, and that's a bad thing - especially in the PHP tag. Deleting this stuff is actually quality control.
If you do not want to risk answering a question that may be deleted, and losing the rep associated with it, refrain from answering it.
