Tag Cloued Modules are really Usefull or can Damage the indexing and rank?

Let me ask you whether these changes, or type the Tags Cloud module of vbadvanced are really useful or penalize the forum as they may be recognized as duplicates or "Meta Tags" excessive in both indicex.

Tag Cloud on Forum Home - vBulletin.org Forum

Nobody want to partecipate in this thread? I think it's an important thing

Personally I think it all depends on how many forums you have.
100 links Max. per page (I think that's the general rule), so if you have 50 forums and say your top 25 tags in a cloud I think it's a plus for SEO (not sure how aesthetically pleasing they are though).

About me the real question is, regardless of the amount of forum and many tags inserted for each thread, although personally I think if they enter more and more it is penalized. Well, said that, and not really knowing how they work on forums (not blogs) with modules that contain the same tag of the forum threads, will not be recognized as duplication and excessive as less "Meta Tags keydords?

If it were, there would be a drastic fall in search engines or even you might enter the sandbox.

I'd like to hear about that some vBSEO devs or super expert in this field (SERP's, SEF, SEO).

Thanks woostar for your intervention.

I think they can be useful, but I wouldn't put it on forumhome. Forumhome is already cluttered with links.

After I upgrade to version 3.7.x of vBulletin from 3.6.x and from vBSEO 3.1 to vBSEO 3.2, this halved the forum visits, and I cannot understand the motivation, now we must interpret the word useful and translate it into technical terms and SEO.
