Thought I'd revisit the list to include all the additions...plus add a new one based on a recent thread...somewhere.
(We're now at three times the size of original post...thanks everyone!)
1. Post a generic question lacking any meaningful details about the issue itself or any details about your car.
Bonus points if you post in a generic (or the incorrect) forum.
2. Include 9 different issues in the same post.
Bonus points if you prepare the post as a long, run-on paragraph.
3. Post the same exact issue in multiple forums.
Bonus points if you also PM certain members with the same issue as in the post.
Variation (Thanks, MB-SV!): Place spam-like postings in multiple places on the same forum....
4. Ask a question seeking opinions, then argue with those who respond.
Bonus points if you don't even own the car you're posting about.
5. Don't use the search function, ever. It's cool to start the 476th thread on the same issue.
Bonus points if you combine this with #3 above.
6. Hijack a useful, meaningful thread with a new and different issue.
Bonus points if you hijack it also for a different model.
Double bonus points if you argue with another member who points out the better course of starting your own thread in the forum where it belongs.
7. Start a thread with "HEEELLLPP" in the subject lane, than present the problem with no info about car model, no location and no car age/mileage (Thanks, Kajtek1).
8. Post a problem along with your suspected solution; then ignore any responses with logical alternate suggestions.
Bonus points for ignoring the greatest number of relevant solutions.
9. Explain how Toyota, ehm... Lexus works and ask for secret codes that would enable the same on any MB (making it equally bad).
10. If the car needs some fixing at the dealer because DIY is not possible without their computers, one could explain how a Toyota and W123 never fail, and how friendly they are for all the DIY repair. (9 & 10, thanks Diesel Benz!)
11. 7. Pull up a dead thread from 2001 to tack your question onto.
Bonus points for trying to give the original poster advice over 6 years later.
12. Sign in as a 'newbie' and ask your question...then either forget where you found Benzworld, or don't bother saying a quick thank you for all the help that members subsequently offer. (Thanks, shrimpton!)
13. Post a noob question that's all over the map, perhaps incorporating some of these other points. When perhaps as much as 30 minutes have elapsed without an answer, post a spiteful reply about how no one helped you.
Bonus points if you posted in the wrong forum.
Double bonus points if someone points this out to you and you reply along the lines of "sure, know-it-all, can't even answer my question huh?"
14. Jump in as a newbie and insult other folks' rides while revealing your ignorance about the make, model or both. (OP)
15. Start a thread and when you come back to follow up, don't post in your original thread but instead start a new thread each time.
Bonus points if you use the same thread title.
Double bonus if you start two or more follow-up threads on the same day.
16. One of the tires on one of my cars keeps getting low on air. Do you think it might be leaking? (Thanks, edfreeman!)
17. Demonstrate the penetrating beauty of this thread by posting a real issue in the middle of it and being perplexed by the baffled/humorous responses.
18. Post about a malfunction warning; when focused responses are posted, only then admit that you were working on something else and may have "accidentally" damaged the thing that are the focus of the responses (which are directly related to the malfunction warning) and that the problem started immediately after your other repair.
Bonus points if you then ignore the responses and take it in for a "professional" opinion...that simply reinforces what you already learned from the forum.
